A Herculean task: Classical simulation of quantum computers

Understand

In the effort to develop useful quantum computers simulating quantum machines with conventional computing resources is a key capability.

• Such simulations will always face limits preventing the emulation of quantum computers of substantial scale but by pushing the envelope as far as possible through optimal choices of algorithms and hardware the value of the simulator tool is maximized.
• This work reviews the state-of-the-art numerical simulation methods i.e.
• the classical algorithms that emulate quantum computer evolution under specific operations.
