arxiv.orgQuantum gates are usefully divided into one- and two-qubit operations. One-qubit gates on hyperfine qubits can be performed with microwaves, two-frequency stimulated optical Raman transitions, or a combination of Stark shifting light and microwaves. We defer a discussion of the current state of the art of one-qubit gate operations to Sec. 5.1 ...

Quantum Gates, Circuits, and Algorithms - NCSU
arcb.csc.ncsu.eduQuantum gates are performed by sending electromagnetic impulses at microwave frequencies to the qubits through coaxial cables. These electromagnetic pulses have a particular duration, frequency, and phase that determine the angle of rotation of the qubit state around a particular axis of the Bloch sphere. Koch, et al.
Quantum Computing - Lecture Notes - University of …
homes.cs.washington.eduquantum computing. Quantum mechanics is a mathematical language, much like calculus. Just as classical physics uses calculus to explain nature, quantum physics uses quantum mechanics to explain nature. Just as classical computers can be thought of in boolean algebra terms, quantum computers are reasoned about with quantum mechanics.
