Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform ...

Many physicists and engineers have recently been trying to demonstrate the potential of quantum computers for tackling some ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

Researchers from the US and the UK have studied the relationship between a quantum algorithm’s runtime and its resilience to noise, with unexpected results Optimising the design of a quantum algorithm ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...
