QuantumATK (formerly Atomistix ToolKit or ATK) is a commercial software for atomic-scale modeling and simulation of nanosystems. The software was originally developed by Atomistix A/S, and was later acquired by QuantumWise following the Atomistix bankruptcy. [ 1 ]
Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods.
However, in quantum computing, operations have the ability to introduce phase changes to quantum states. This is the basis for complex interference patterns and quantum entanglement. When a controlled operation, such as a Controlled NOT (CNOT) gate , is applied to two qubits, the phase of the second (target) qubit is conditioned on the state of ...
Possibly the greatest development in the broader digitalization sphere, quantum computers feature the potential to change everything we know about machine-driven calculations, thus auguring very ...
Quantum Trajectory Theory (QTT) is a formulation of quantum mechanics used for simulating open quantum systems, quantum dissipation and single quantum systems. [1] It was developed by Howard Carmichael in the early 1990s around the same time as the similar formulation, known as the quantum jump method or Monte Carlo wave function (MCWF) method, developed by Dalibard, Castin and Mølmer.

Extending () to a rotation about a generic phase of both basis states of a 2-level quantum system (a qubit) can be done with a series circuit: () = []. When α = − β {\displaystyle \alpha =-\beta } this gate is the rotation operator R z ( 2 β ) {\displaystyle R_{z}(2\beta )} gate and if α = β {\displaystyle \alpha =\beta } it is a global ...
Quantum finance is an interdisciplinary research field, applying theories and methods developed by quantum physicists and economists in order to solve problems in finance. It is a branch of econophysics .
Target on Wednesday reported sluggish sales and slumping profits in the fiscal third quarter as inflation-weary customers curtailed their spending on apparel and other non-essential items.
