IBM's Quantum Computing Fridges: Cooling Down Complexity
IBM is working to advance the capabilities of quantum computers by making them more stable and increasing their processing power. To achieve this, the company has developed new Modular Cryogenic Systems, or 'super refrigerators,' that can keep qubits, the fundamental units of quantum computing, at a temperature just a few thousandths of a degree above absolute zero.
The fridges are designed to maintain an ultra-cold environment free from heat, vibrations, radiation, and other interference. They are so cold that it takes around five days for them to reach the required temperature, which is more than 180 times colder than deep space.
IBM plans to use these systems in conjunction with L-coupler superconductor cables, which connect qubits inside the modular system without causing them to lose their quantum properties. The company aims to install a working processor chip containing hundreds of qubits inside one of these fridges by the end of this year and to have a larger computer made up of at least 1,000 programmable qubits by next year.
Eventually, IBM plans to construct a system of 12 connected cryogenic fridges and 50 processor chips working in tandem. This will enable quantum computers to tackle complex problems such as molecular chemistry, drug development, and materials science with greater accuracy and efficiency.
