While universal quantum computing may be decades away, the military is working on a hybrid system that combines the best of quantum computing with the stability of classical systems, reports Joseph Farah’s G2 Bulletin.
The Defense Advanced Research Projects Agency has planned a meeting for those interested in working on its Optimization with Noisy Intermediate-Scale Quantum devices program.
The aim is to “exploit quantum information processing before fully fault-tolerant quantum computers exist.”
“The problem is the performance and reliability of quantum devices depend on the length of time the underlying quantum states can remain coherent. If you wait long enough, interactions with the environment will make the state behave like a conventional classical system, removing any quantum advantage. Often, this coherence time is significantly short, which makes it difficult to perform any meaningful computations,” the agency explained.
The agency, with the help of interested parties, will pursue “a hybrid concept that combines intermediate-sized quantum devices with classical systems to solve a particularly challenging set of problems known as combinatorial optimization.”
