Quantum physicists have developed an algorithm that uses a single qubit to solve a problem that had previously needed thousands of them.
A silent symphony is playing inside your brain right now as neurological pathways synchronize in an electromagnetic chorus that’s thought to give rise to consciousness.
Yet how various circuits throughout the brain align their firing is an enduring mystery, one some theorists suggest might have a solution that involves quantum entanglement.
The proposal is a bold one, not least because quantum effects tend to blur into irrelevance on scales larger than atoms and molecules. Several recent findings are forcing researchers to put their doubts on hold and reconsider whether quantum chemistry might be at work inside our minds after all.
Jim Clarke, Director of Quantum Hardware at Intel Labs, discusses how chemistry and physics drive the development of qubits in these unique systems. These systems will bring mind-blowing computing power to the world in the next decade and beyond.

In the famous double-slit experiment, an interference pattern consisting of dark and bright bands emerges when a beam of light hits two narrow slits. The same effect has also been seen with particles such as electrons and protons, demonstrating the wave nature of propagating particles in quantum mechanics.
Researchers are studying how quantum computers can help optimise net-zero power grid operation and expansion planning.
Unlike classical encryption, which relies on mathematical algorithms, quantum encryption assures security based on physical principles. Detection of espionage or interference is guaranteed by unavoidable alteration of the quantum states involved.
Quantum computing is one of those “just around the corner” technologies that have the scientific community split. Tech outfits such as Google and IBM have gone full throttle with both research and development and marketing as if they’re already here, while many independent researchers have claimed quantum computers will never work.
Most people working in the field, however, believe that quantum computers will be able to solve problems that classical computers can’t solve within the next 10 years.
This is according to a recent survey of 927 people with associations to the field of quantum computing (researchers, executives, press, enthusiasts, etc.) conducted by QuEra. Of those surveyed, 74.9% “expect quantum to be a superior alternative to classical computing for certain workloads” within the next 10 years.
Photon Bose–Einstein condensation is observed in a semiconductor laser, where thermalization and condensation of photons occur using an InGaAs quantum well and an open microcavity. The distinction between regimes of photon Bose–Einstein condensation and conventional lasing are clearly identified.
Researchers wish to probe whether consciousness has a basis in quantum mechanical phenomena.
Quantum computers have the potential of outperforming conventional computers on some practically relevant information processing problems, possibly even in machine learning and optimization. Yet their large-scale deployment is not yet feasible, largely due to their sensitivity to noise, which causes them to make errors.
