Researchers from the University of Sydney, working with IBM, have identified and quantified important factors limiting the ...

For their latest magic trick, physicists have done the quantum equivalent of conjuring energy out of thin air. It’s a feat that seems to fly in the face of physical law and common sense. “You can’t ...

Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist ...

Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their ...

for error-corrected surface code logical qubits 3,4,13. Here d is the code distance indicating 2d 2 − 1 physical qubits used per logical qubit; p and ε d are the ...

In this paper, we report an experimental demonstration of training DQNNs through the BP algorithm on a programmable superconducting processor with six frequency-tunable transmon qubits. We find that a ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...

Quantum sensing is primed for a breakout that will radically change both conventional and nuclear warfare, requiring essential reforms for the Department of Defense (recently renamed to the Department ...

Quantum physics is the “study of matter and energy at the most fundamental level.” Quantum technologies exploit the properties identified by quantum physics to provide new capabilities in computing, ...
