Microsoft has crazy quantum computing plans. It is building hardware based on a particle that hasn't been discovered, and the company now wants to make super-cool memory for quantum computers.
The company is working with Rambus to develop and build prototype computers with memory subsystems that can be cooled at cryogenic temperatures. Cryogenic temperatures typically are below minus 180 degrees Celsius or minus 292 degrees Fahrenheit.
Quantum computers could eventually replace today's PCs and servers and promise to be significantly faster. But the systems are notoriously unstable and need to be stored in refrigerators for faster and secure operation. As an example, D-Wave's 2000Q quantum computer needs to be kept significantly cooler than supercomputers so operations don't break down.
