Today I want to show you how to write code for a quantum computer using Google’s Cirq. In 2019, Google announced that they have reached quantum advantage. Quantum advantage means that we have reached a threshold where a quantum computer can do something faster than a classical computer. This is HUGE for the field of quantum computing.

The Sycamore 54 qubit device was the one used for the arguably most famous quantum computing paper so far, Quantum Supremacy using a Programmable Superconducting Processor. As of right now, the Cirq code does not have access to the real Google quantum computer yet, unless you are an early partner in their program. Google has stated that they will welcome a new set of partners in 2021, so, even though you may not have access to the machines now, you can still use their programming language to build algorithms and use the quantum simulator to test out your circuits.
