A quantum algorithm, however, runs on a quantum computer, which uses quantum bits (or qubits). Unlike bits, qubits can represent 0 and 1 at the same time, due to a property called superposition.

Many quantum computing companies currently have systems that are only measured in the hundreds of qubits. However, Google's own long-term roadmap is targeting systems with a million or more qubits.

Quantum adiabatic and quantum circuit algorithms are equivalent, say physicists To test their approach, Green and colleagues simulated an Ising spin chain, which is a large one-dimensional quantum ...

Quantum algorithms must be implemented by a quantum computer, and in 1996, when Grover did his work, these were little more than a distant dream. But the breakthrough came quickly.

NIST announced three of the four proposed quantum-resistant encryption algorithms this week: CRYSTALS–Kyber, CRYSTALS–Dilithium, and SPHINCS+. The fourth one, FALCON, might be released next year.

Those algorithms are ways of working out the lowest energy state, or "ground state" of the quantum system. The team says that QAOA is an important example of this type of quantum algorithm.

Today’s quantum computing recipes are complex (see, for instance, J.P. Morgan Chase’s algorithm for option pricing with quantum) and implementation challenges are inevitable.

David S. Linthicum is an internationally recognized industry expert and thought leader. Dave has authored 13 books on computing, the latest of which is An Insider’s Guide to Cloud Computing.

Using a quantum algorithm, called the Binary Quadratic Model (BQM) that can run on different quantum platforms, the team decided to test two markedly different models: D-Wave's quantum annealing ...
