The language also supports macro-like definitions of possibly parametrized quantum circuits and their expansion, qubit measurement and recording of the outcome in classical memory, synchronization with classical computers with the WAIT instruction which pauses the execution of a Quil program until a classical program has ended its execution ...
According to Geordie Rose, founder and Chief Technology Officer of D-Wave, NP-complete problems "are probably not exactly solvable, no matter how big, fast or advanced computers get"; the adiabatic quantum computer used by the Orion system is intended to quickly compute an approximate solution.

This article lists the companies worldwide engaged in the development of quantum computing, quantum communication and quantum sensing. Quantum computing and communication are two sub-fields of quantum information science , which describes and theorizes information science in terms of quantum physics .
Current quantum computers on the market are too small and make too many errors to be used for commercial gain. However, Google's recent development has demonstrated a significant reduction in the ...
Google’s Willow findings show that quantum computers can perform much better than the best available supercomputers in certain cases, an assertion that just a few years ago was more widely doubted.
Rigetti Computing was founded in 2013 by Chad Rigetti, a physicist with a background in quantum computers from IBM, and studied under Michel Devoret. [ 2 ] [ 3 ] The company emerged from startup incubator Y Combinator in 2014 as a so-called "spaceshot" company.
A quantum computer is controlled by a classical computer, and behaves like a coprocessor that receives instructions from the classical computer about what gates to execute on which qubits. [13]: 42–43 [14] Classical control is simply the inclusion, or omission, of gates in the instruction sequence for the quantum computer.
