Best-yet quantum simulator with 53 qubits could really be useful

A 53-qubit quantum simulator is the biggest of its kind, and has already done some calculations that outperform most, if not all, classical computers

We’re two qubits closer to useful quantum computers. That might not sound like much, but in the quantum computing arms race, several groups are edging past one another as they aim to eventually make a universal quantum computer.

A group of researchers at the Joint Quantum Institute has created a quantum simulator  using 53 quantum bits, or qubits. Earlier this month, IBM announced a 50-qubit prototype, though its capabilities are unclear.

With this 53-qubit device, the researchers have done scientific simulations that don’t seem to be possible
