Researchers have announced that they have produced what is called a “time crystal” using the qubits in Google’s Sycamore quantum computer, a breakthrough that means that stable qubits can be built to power insanely fast quantum computers in the future. While the term “time crystal” might evoke images of quartz-likeread more

An international team of researchers has definitively proven that quantum computers can hold a significant computational advantage over classical semiconductor-based computers.

Although quantum computing elements have been available in D-Wave Systems‘ series of computers for over a decade, there has been a great deal of controversy over whether or not the performance increases demonstrated by these computers are actually due to quantum processes, and not simply efficiencies hidden in the computer’s code or hardware.
