Microsoft quantum computing ‘breakthrough’ faces fresh challenge
A physicist has cast doubt on a test that underlies a high-profile claim by Microsoft to have created…
Fresh ‘quantum advantage’ claim made by computing firm D-Wave
]]> A ‘quantum processor’ has solved a physics problem on the behaviour of magnetism in certain solids that…
Unconditional advantage of noisy qudit quantum circuits over biased threshold circuits in constant depth
Background In this paper, we consider classes of shallow-depth quantum circuits—circuits of constant depth independent of the input…
more complex cousins of qubits boost quantum computing
Part of the quantum computer at Innsbruck University on which researchers did simulations using qutrits and ququints. Credit:…
