NIST researchers have developed the first “universal” programmable quantum processor capable of running any quantum program using two qubits. This processor could be a building block for future quantum computers, which could solve complex problems intractable for classical computers.
The NIST processor uses two beryllium ions stored in an electromagnetic trap and manipulated with lasers. Scientists can place the ions in a superposition of 1 and 0 states simultaneously and entangle them. The processor ran 160 different programs, demonstrating its universality. Each program operated accurately 79% of the time on average.
Quantum computers have potential applications in breaking encryption codes and simulating quantum systems for understanding phenomena like high-temperature superconductivity. The research was supported by DARPA, NSA, and IARPA.
