You might be familiar with the qubit, the fundamental unit of quantum information. As its name suggests, a qubit in a quantum computer performs the same function as a bit in a classical computer, with ...

Quantum computers, which operate leveraging quantum mechanics effects, could soon outperform traditional computers in some advanced optimization and simulation tasks. Most quantum computing systems ...

Researchers have demonstrated that the theoretically optimal scaling for magic state distillation—a critical bottleneck in fault-tolerant quantum computing—is achievable for qubits, improving on the ...

A research team led by Prof. GUO Guangcan, Prof. SHI Baosen and Prof. DING Dongsheng from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) achieved ...

Quantum computers promise dramatic advantages over their classical counterparts, but the source of the power in quantum computing has remained elusive. Here we prove a remarkable equivalence between ...

The study of elementary particles and forces is of central importance to our understanding of the universe. Now a team of physicists from the University of Innsbruck and the Institute for Quantum ...
