'We're entering this phase of quantum computing that I call... the era of utility.'
"quantum supremacy" when its scientists claimed they demonstrated that their quantum computer could outperform a classical one.
Basically, it takes advantage of two principles of quantum mechanics. The first is superposition, the ability for a single particle, in this case quantum bits or qubits, to be in two separate states at the same time. Then there's entanglement, which enables two particles to share the same state simultaneously.allow for a far smaller number of qubits to rival the processing power of regular bits, which can only be a binary one or zero.
This is where IBM's new work comes in. In the experiment, the company's researchers used a 127 qubit IBM Eagle processor to calculate what's known as an Ising model, simulating the behavior of 127 magnetic, quantum-sized particles in a magnetic field — a problem that has real-world value but, at that scale, is far too complicated for classical computers to solve.noise, and then precisely documented its effects on each part of the processor's circuit and the patterns that arose.
There's just one nagging problem. Since the calculations the IBM quantum processor performed were at such a complicated scale, a classical computer doing the same calculations would also run into uncertainties.
