Quantum Computing at Johns Hopkins APL 

Quantum computing is a growing field of research. The Johns Hopkins Applied Physics Lab is on the cutting edge of quantum research. Quantum computer uses quantum bits, or qubits, which can not only take values of zero one but can also take superpositions between these two values, and that gives a lot of power to the types of computations one can do. However, coming up with methods to deal with noise in the quantum setting can be very challenging.
APL is focusing on tackling the problems associated with that noise, or molecular fluctuation in the quantum realm. Those fluctuations kill quantum mechanical behavior, so the temperature needs to be about six thousandth of a degree above absolute zero and at low enough temperatures
to isolate that system from its environment and treat it like a quantum mechanical system.
That's where the super chill refrigerator comes in. It uses a combination of helium-3 and helium-4 to reach temperatures of near absolute zero. Bundling qubits into the fridge and chilling down takes hours. Then the research into eliminating quantum noise begins. That needs to happen in order to build large-scale quantum computers.
