In a room on the United Kingdom’s University of Plymouth, a Ph.D. scholar is sitting at a pc, eyes closed as if he’s meditating. On his head is what seems to be like a black swimming cap, however is definitely an electroencephalogram (EEG) reader that’s sensing {the electrical} exercise passing over his scalp. In entrance of him, on the monitor, there’s a picture of a wireframe globe with two factors marked “1” and “0.” In the middle of the globe, like a clock with a single hand, is an arrow that oscillates between the 2 factors. As the scholar adjustments his expression from one in all leisure to one in all wide-eyed agitation, the arrow twitches and strikes. Every a number of seconds, he enters a brand new digit.
It won’t seem like a lot (and proper now, it’s nonetheless very early days for this work), but it surely’s nonetheless fascinating stuff. As the scholar adjustments his mind patterns from calm to energized and again once more, he produces alpha and beta waves which are then used to control simulated qubits – the basic unit in quantum computing, reflecting the maths of quantum physics – utilizing nothing greater than the facility of thought.
“If you train yourself to produce these two kinds of waves, then you can send some sort of Morse code to the computer,” professor Eduardo Miranda of the University of Plymouth instructed Digital Trends. “The problem is that it takes eight seconds to generate one command at the moment because the EEG is very slow. We need a lot of processing to analyze it. And this analysis is not so accurate, so we need to keep checking many times to see if the code really is what the person wants to produce.”
Welcome to the considerably shaky, tentative steps of the world of quantum programming by the use of brain-computer interface. According to its creators, it’s the beginning of building of what the workforce calls the Quantum Brain Network (abbreviated to QBraiN). And it’s obtained the potential to do a bunch of issues which are price getting enthusiastic about.
More than the sum of its components or a toaster-fridge?
If you’ve seen any listing of probably the most thrilling applied sciences presently shimmering on the tech horizon, you’ve nearly definitely come throughout the phrases brain-computer interface (BCI) and quantum pc.
A BCI is fancy terminology for a method of controlling a pc utilizing mind indicators. While each system with a guide enter is technically managed by the mind – albeit normally through an middleman like fingers or voice – a BCI makes it attainable to ship these instructions to the surface world with out having to first output from the mind to peripheral nerves or muscle tissues.

Quantum computer systems, in the meantime, symbolize the Next Big Thing in computing. First proposed within the 1980s, though solely now beginning to turn out to be a technical actuality, quantum computing refers to a very new method to pc structure. It is not going to solely be much more highly effective than present classical computer systems, however will even make it attainable to realize issues that may be inconceivable even with hundreds of thousands of in the present day’s supercomputers chained collectively. They might, in case you imagine their proponents, be the reply to the inevitable finish of Moore’s Law as we all know it.
However, whereas BCIs and quantum computer systems are undoubtedly promising applied sciences rising on the identical level in historical past, the query is why convey them collectively – which is strictly what the consortium of researchers from the U.Ok.’s University of Plymouth, Spain’s University of Valencia and University of Seville, Germany’s Kipu Quantum, and China’s Shanghai University are looking for to do.
Taking two must-have applied sciences and mixing them doesn’t all the time work, although.
Technologists love nothing greater than mashing collectively promising ideas or applied sciences within the perception that, when united, they may symbolize greater than the sum of their components. Sometimes this works gloriously. As the enterprise capitalist Andrew Chen describes in his ebook The Cold Start Problem, Instagram leveraged the emergence of camera-equipped smartphones and the simultaneous highly effective community results of social media to turn out to be one of many fastest-growing apps in historical past.
Taking two must-have applied sciences and mixing them doesn’t all the time work, although. Apple CEO Tim Cook as soon as quipped that “you can converge a toaster and a refrigerator, but, you know, those things are probably not going to be pleasing to the user.”
So what makes brain-controlled quantum computing an instance of the previous, a member of the more-than-the-sum-of-its-parts membership, and never symptomatic of the toaster-fridge drawback? In a paper revealed in early 2022, the aforementioned consortium of researchers write that: “We foresee the development of highly connected networks of wetware and hardware devices, processing classical and quantum computing systems, mediated by brain-computer interfaces and A.I. Such networks will involve unconventional computing systems and new modalities of human-machine interaction.”
Use circumstances galore
The most vital – and, if it really works, instantly transformative – utility of the Quantum Brain Network is that it’s going to assist BCIs to work higher. Our brains are extremely complicated. They boast 100 billion neurons, forming large networks with quadrillions of connections in fixed communication with each other through tiny electrical impulses. Today, science is able to recording the best way components of the mind talk, from the smallest neuron-to-neuron interplay to bigger communications between neuron networks.
But doing this sometimes concerned extremely specialised expertise, reminiscent of useful magnetic resonance imaging (fMRI), that’s solely accessible in high analysis labs. The BCI experiments that depend on the blunt instrument of EEG are typically comparatively simplistic in what they’ll do: Say, deciding whether or not an individual is considering of the colour blue or pink, or making a drone transfer up and down or left and proper. They lack nuance.

That’s now altering, Miranda defined. “We are beginning to have access to good hardware. Increasingly better EEG scanning is coming out.”
Better mind wave-sensing {hardware} is just one piece of the puzzle, although. As an analogy, think about having a very correct microphone positioned in the midst of a soccer stadium. The microphone is so highly effective that it’s in a position to choose up each sound made by the 1000’s of followers within the stadium, no matter whether or not they’re cheering loudly or quietly munching on a hotdog. However, as spectacular as this could be, with out the proper audio-filtering software program, you’d be unable to do greater than take heed to an aggregated, shapeless mass of crowd noise. On its personal, such a microphone wouldn’t aid you decide, for instance, what’s being stated by the individual in seat 77A.
What you want isn’t simply the flexibility to report this data, but in addition to decode it and make it helpful. And rapidly. This is what quantum computing might do through the use of its superior talents to assist higher course of the unimaginable amount {of electrical} mind impulses which are wanted to grasp intentions and ideas as they happen.
“BCI needs real-time control,” Miranda continued. “I think quantum computing can provide the speed we need to do this processing… [Right now] we can’t figure out what all this messy information we are getting with the EEG means. If we could, then we could begin to classify the signals and label certain behaviors that we force ourselves to produce.”

Perhaps straining to provide these behaviors wouldn’t even be needed. As Azeem Azhar writes in his 2021 ebook Exponential, the promise of brain-computer interfaces is to have the ability to “pluck neural activity from our heads even before it forms into thought.” Just like recommender techniques – reminiscent of these employed by Spotify, Netflix and Amazon – search to indicate us what we need to devour earlier than we’ve even determined for ourselves, so too will BCIs learn our barely acutely aware thought patterns and extrapolate helpful data from them.
That could possibly be controlling a sensible dwelling or a robotic, popping up the proper contextual data on the proper second, or offering extra fine-grained motion to a neural-controlled prosthesis. In Miranda’s pet use case, one he’s been engaged on for years, it might assist individuals with locked-in syndrome to raised talk quickly with the surface world.
The quantum metaverse?
Then there’s the opportunity of utilizing the mind to work together with a quantum pc itself, reasonably than simply utilizing it to bootstrap processing. “In the future, it may be possible to affect quantum states in a quantum machine with mental states,” stated Miranda. “I will not go as far as saying that we’ll be able to entangle our brain with quantum computers, but we will be able to have a more direct communication with quantum states.”
That could possibly be programming a quantum pc not within the clunky method of the demonstration, however just by considering of a desired output and letting the machine program the proper code immediately. Picture it like evolutionary computing (the place you state a desired output and let the machine determine the artistic path to it) on superposition steroids.

Some of the researchers on the venture are additionally excited on the prospect of making what they time period a quantum metaverse. (And in case you assume the present idea of the common metaverse is fuzzy across the edges, attempt to wrap your head round its quantum equal!). Somehow, although, the thought makes a variety of sense. A.I. researchers have lengthy imagined – and, actually, this underpins your entire notion of true synthetic intelligence – that the wetware of the mind could possibly be recreated via {hardware} and software program. Since at the least the 1990s, some main physicists and mathematicians have been arguing that the character of consciousness is, in actual fact, quantum.
For instance, a 2011 paper co-authored by the world-renowned Oxford mathematical physicist Roger Penrose argues that “consciousness depends on biologically orchestrated quantum computations in collections of microtubules within brain neurons, that these quantum computations correlate with and regulate neuronal activity, and that the continuous Schrödinger evolution of each quantum computation terminates in accordance with the specific Diósi–Penrose (DP) scheme of ‘objective reduction’ of the quantum state.”
“There is a lot of philosophical debate going on saying that the brain functions as a quantum computer,” Miranda defined. “People are dreaming that perhaps it’s possible that if we managed to connect our brains with a quantum machine, then we become an extension of the machine or the machine becomes an extension of our brain.”
(Miranda stated that he’s not personally “entirely convinced” by the argument that brains act like quantum computer systems.)
Step one in a protracted journey
For now, a lot of that is far-off – and far-out. Advances will have to be made in a number of areas: The availability of quantum computer systems (the demo described earlier was carried out utilizing a simulated quantum pc), the usefulness of quantum algorithms, continued enhancements in brain-reading expertise, and way more.
The subsequent step, stated venture participant professor Enrique Solano, director of the analysis group Quantum Technologies for Information Science (QUTIS), is “to go for a trapped-ion [quantum computer] or one based in spin qubits, which work at room temperature, and assure that latency and coherence times become compatible.”
Opening this Pandora’s Box of brain-controlled quantum computing goes to be troublesome. We’re speaking about years earlier than this turns into sensible for greater than only a few promising demos. But the largest improvements typically take time.
“The brain is the most complex object we know up to now in the universe,” Solano instructed Digital Trends. “In this sense, if you connect it with a primitive interface, you have to accept an oversimplified model of it with minimal biological and intelligent features.”
Quantum computing will be the answer to that drawback. Welcome to the Quantum Brain Network, certainly.
