An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

Sometimes a visually compelling metaphor is all you need to get an otherwise complicated idea across. In the summer of 2001, a Tulane physics professor named John P.

Add Yahoo as a preferred source to see more of our stories on Google. A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with ...

Science is always looking for more computing power and more efficient tools capable of answering its questions. Quantum computers are the new frontier in data processing, as they use the quantum ...

This post is part 1 of a series. It is coauthored by Liane Gabora, Emmanuel Pothos, and Iana Bashmakova. There is a trend toward increased openness in science, and one aspect of this involves sharing ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...

Classical computations rely on binary bits, which can be in either of the two states, 0 or 1. In contrast, quantum computing is based on qubits, which can be 0, 1, or a superposition or entanglement ...
