(2021)). That is, in quantum circuits, the logic gates modify not the usual binary 1 or 0 bits, but qubits, the fundamental unit of quantum computing (Matthews, 2021). Qubits come from carefully chosen few state quantum systems, such photon polarizations, atomic hyperfine states, ...
Introduction to Quantum Information Science Lecture Notes, which has 259, pages has assumes that a reader has knowledge of linear algerbra and some knowledge of classical algorithms. It then explains many of the basic concepts of quantum computing as ...

states. Finally, a laser was used to entangle the particles, creating a superposition of both spin-up and spin-down states simultaneously for all four ions. Again, this approach demonstrated basic principles of quantum computing, but scaling up the technique to practical dimensions remains ...
Quantum computing Used by specialized and experimental quantum mechanics-based quantum hardware. Stores information in qubits as 0, 1 or a superposition of 0 and 1. Processes data with quantum logic at parallel instances, relying on interference. Quantum processors do not perform mathematical equations...
this post dives somewhat deep into a few of the scientific details of building larger and more useful quantum computers. The level of the material is aimed at technical or science staff in the quantum computing industry and graduate-level or higher students and researchers in quantum computing. ...
Quantum Gates We’re back in familiar territory. In classical computing we use logic gates to operate on bits, and likewise we can use quantum gates to operate on qubits. Think of the NOT gate, which takes 0 → 1 and 1 → 0. A quantum NOT gate bears some resemblance to it...
quantum dot device to a one-dimensional qubit array, as shown in Fig 1. “The 300 mm fabrication platform is the first versatile hardware toolbox that allows such flexible qubit device designs”, says Iuliana Radu, program director at imec, where she is leading the quantum computing activities...
Fast and high-fidelity two-qubit logic gates are demonstrated by using amplitude-shaped laser pulses to ensure that the gate operation is insensitive to the optical phase of the pulses. Among the technologies that hold promise for quantum computing, trap
