Is there a working quantum computer?
In October 2019, Google AI Quantum, with the help of NASA, became the first to claim to have achieved quantum supremacy by performing calculations on the Sycamore quantum computer more than 3,000,000 times faster than they could be done on Summit, generally considered the world’s fastest computer.
What are quantum dots in quantum computing?
Quantum dots are nanoparticles so small that their electronic properties are governed by quantum mechanics. Pairs of quantum dots can serve as a single basic element in a quantum logic device, called a quantum bit or qubit. Silicon qubits can be made to hold just one or a few electrons.
