“High-fidelity control of quantum bits is paramount for the reliable execution of quantum algorithms and for achieving fault tolerance—the ability to correct errors faster than they occur. The central ...

Google successfully used quantum error correction in practice, opening the door to large quantum computers with vast capabilities. The team used a surface code to ...

One of the biggest stumbling blocks for quantum computers is their tendency to be error-prone and the massive computational overhead required to clean up their mistakes. IBM has now made a ...

Many experts predict that practical fault tolerant quantum computing (FTQC) will require millions of physical quantum bits (qubits) but in August, 2023 IBM scientists ...

The quantum low-density parity check (QLDPC) codes, the “holy grail” of quantum error correction research and development for 30 years, have a breakthrough ...

Chinese researchers have taken a major step in the global race to build practical quantum computers, becoming the first team outside the United States – and the second in the world after Google – to ...

While quantum computers are already being used for research in chemistry, material science, and data security, most are still too small to be useful for large-scale applications. A study led by ...

Why it matters: New research from the University of California, Riverside, marks an important shift in quantum hardware design. Rather than waiting for flawless quantum chips and connections, ...
