It’s not easy to study quantum systems — collections of particles that follow the counterintuitive rules of quantum mechanics. Heisenberg’s uncertainty principle, a cornerstone of quantum theory, says ...

A major problem with quantum computers is memory, as the information they contain can be quickly lost. Quantum computers are ...

The original version of this story appeared in Quanta Magazine. It’s not easy to study quantum systems—collections of particles that follow the counterintuitive rules of quantum mechanics.

Dr. Dominic Williamson, a University of Sydney quantum physicist, has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

For over two decades, physicists have been working toward implementing quantum light storage—also known as quantum memory—in various matter systems. These techniques allow for the controlled and ...

Quantum technologies operate by leveraging various quantum mechanical effects, including entanglement. Entanglement occurs when two or more particles share correlated states even if they are distant.

Quantum computing is moving from physics labs into real hardware, promising to attack problems that overwhelm even the fastest supercomputers. Among the boldest claims is that these machines could ...

In the fast-evolving world of quantum computing, one of the biggest hurdles isn’t how fast calculations can be done—it’s how long you can hold onto the delicate quantum information in the first place.

In the bustling tech hub of Taiwan, where semiconductor giants and cutting-edge manufacturers dominate the landscape, a different kind of computing revolution is slowly taking shape. Quantum computing ...
