In these, the qubits are a string of ions held in place by an electric field and manipulated using pulses of laser light. They turned to a quantum computer prototype called an ion trap. “It's the kind of thing that I'm sure governments will not appreciate very much-encryption that is guaranteed by the laws of physics” The thrust of their work underpins the most widely used encryption method in the world called the RSA algorithm. Hellman, won the 2015 Turing Award, the highest honor in computer science. On Tuesday, two pioneers of this method, Whitfield Diffie and Martin E. Computers have traditionally struggled to do the calculations based on factoring, so data transferred in this way remains secure. Much of the world’s digital data is currently protected by public key cryptography, an encryption method that relies on a code based partly in factoring large numbers. Now computer scientists at MIT and the University of Innsbruck say they've assembled the first five quantum bits (qubits) of a quantum computer that could someday factor any number, and thereby crack the security of traditional encryption schemes. But their amazing mathematical skills may also create grave security risks for data that has long been safely guarded by the premise that certain math problems are simply too complex for computers to solve.
Quantum computers are often heralded as the future of smarter searching and lightning fast performance.
