This is what fun looks like for a particular set of theoretical chemists driven to solve extremely difficult problems: Deciding whether the electromagnetic fields in molecular polaritons should be ...

Quantum simulation and information processing systems harness the principles of quantum mechanics to replicate complex physical phenomena and perform computations beyond the reach of classical devices ...

Artistic representation of the implemented photonic experiment in which entanglement between the polarizations of single photons is mediated by the independent degree of freedom of the photon path.

As the global semiconductor industry enters the so-called 2-nanometer process era, the actual size of transistors—the core ...

Dr Joshua Heath says there is no conclusive, widely-accepted evidence yet of quantum computers outperforming classical ones.

Physicists have built a new type of digital-analogue quantum simulator in Google’s laboratory, which can be used to study physical processes with unprecedented precision and flexibility. Two ...

Simulations show which 2D transistor designs best control leakage as devices shrink, helping guide future chip scaling below ...

An unprecedently large quantum simulator could shed light on how exotic, potentially useful quantum materials work and help us optimise them in the future. Quantum computers may eventually harness ...

Theoretical physicists studying quantum fields in curved spacetime have built a growing body of calculations showing that ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The recently rediscovered idea of quantum jamming complicates things. For the ...

Leading organizations are no longer waiting for quantum computing to mature, instead they're building knowledge, assessing ...
