Synthetic diamonds key to quantum computing

Researchers at Princeton University, working with the Gemological Institute of America, have devised a way of implanting specific “flaws” in synthetic diamonds, which, when activated electrically, function as quantum “repeaters”, allowing signals to be encoded and decoded at a distance. The strange phenomenon of “quantum entanglement”, where distant particles fluctuate identically, has been known for some time, but practical applications have been difficult to develop. This sounds like a big breakthrough in the field, possibly leading to ultra-fast computers and secure communication tools. Here’s a summary of the research:
