#Quantum error correction and quantum foundation how to

Our community isn't yet at the stage where we have a fully encoded logical qubit, but there is a global research effort under way trying to work out how to get us there, how we can make QEC more efficient, and what can be done in the interim.ДЇor near-term technology - what CalTech's John Preskill has called Noisy Intermediate-Scale Quantum technology - quantum error correction is not required but errors remain a major concern. This procedure protects the integrity of the original quantum information even while the quantum processor runs - but at a cost.Дepending on the nature of the hardware and the type of algorithm you choose to run, the ratio between the number of physical qubits you need to support a single logical qubit varies - but current estimates put it at about 1000 to one. QEC is a process whereby the quantum information stored in a single qubit is distributed across other supporting qubits we say that this information is 'encoded' in a logical quantum bit. Much of the great promise supporting our community's aspirations for quantum computing at-scale, and in the long term, comes from quantum error correction (QEC). But there are many successes to be achieved along the way.

Building a universal quantum computer with millions of entangled, coherent quantum bits running complex algorithms is not going to be simple or straightforward. The journey to realizing functional quantum computers will be long and it's a path that Q-CTRL is committed to making as easy as possible for you.ДЄnd by easy, we mean less difficult.
