Quantum Computing Demands a Whole New Kind of Programmer

[![](/img/2017/05/quantum-computing-whole-new-kind-of-programmer-1-1068x601.jpg)](https://singularityhub.com/2017/05/09/quantum-computing-demands-a-whole-new-kind-of-programmer/)Quantum computers finally seem to be coming of age with promises of “quantum supremacy” by the end of the year. But there’s a problem—very few people know how to work them. The bold claim of achieving "quantum supremacy" came on the back of Google unveiling a new quantum chip design. The hyperbolic phrase essentially means building a quantum device that can perform a calculation impossible for any conventional computer. The technology has a major challenge to overcome.

Nanofridge could keep quantum computers cool enough to calculate

Quantum computers need to be kept cool, just like regular computers, but an ordinary fan won’t cut it. A nanofridge that sorts electrons by temperature just might keep it cool enough to allow quantum compute. Classical computers require built-in fans and other ways to dissipate heat, and quantum computers are no different. Instead of working with bits of information that can be either 0 or 1, as in a classical machine, a quantum computer relies on “qubits”, which can be in both states simultaneously – called a superposition – thanks to the quirks of quantum mechanics.
