Quantum Computers And CMOS Semiconductors: A Review And Future Predictions


With the advent of quantum computing, the need for peripheral fault-tolerant logic control circuitry has reached new heights. In classical computation, the unit of information is a “1” or “0”. In quantum computers, the unit of information is a qubit which can be characterized as a “0”, “1”, or a superposition of both values (known as a “superimposed state”). The control c... » read more

Circuit knitting Based On Quasiprobability Simulation


New paper "Circuit knitting with classical communication, " from researchers at ETH Zurich and IBM Quantum.
