An algorithm is a step-by-step procedure to perform a calculation, or a sequence of instructions to solve a problem, where each step can be performed on a computer. Therefore, an algorithm is a quantum algorithm when it can be performed on a quantum computer. In principle it is possible ...

What Is Quantum Computing? Quantum computing is a type of computation that leverages the principles of quantum mechanics to process information far more efficiently than classical computers. While classical computers use bits as the basic unit of data—representing either a 0 or a 1—quantum computer...
What is quantum? The quantum in "quantum computing" refers to the quantum mechanics that the system uses to calculate outputs. In physics, a quantum is the smallest possible discrete unit of any physical property. It usually refers to properties of atomic or subatomic particles, such as ...
NISQ machines are useful for quantum experimentation and algorithm development and have done much to advance the technology. However, they lack the scale to exceed the computational capabilities and practicality of classical computers -- a milestone calledquantum advantagethat is the holy grail of devel...
What is Quantum Computing? Quantum computing is a rapidly emerging field incomputer sciencethat focuses on how to use the unique properties of quantum mechanics to perform mathematical calculations and solve computational problems faster and more efficiently than classical computers that useBoolean logic. ...
Quantum computing is a new approach to calculation that uses principles of fundamental physics to solve extremely complex problems very quickly.
Anything that extends the quantum algorithm beyond that of a classical algorithm is unlikely to be considered prima facie technical under the UK law. Furthermore, the UK patent office has been very willing to apply existing practice to other, cutting-edge algorithms. For example, the UK patent ...
In most algorithms, the readout results require post-processing by a conventional computer to interpret the data as a meaningful solution. Finding quantum circuits that can generate meaningful results using as few qubits and gates as possible is one of the main challenges in quantum algorithm ...
