Researchers have built the first programmable quantum computer with 79% accuracy in results, according to a paper published in Nature. This universal quantum computer is such a device that can simulate any physical system. Unlike the Bit computing system we use today, quantum computing makes use of qubits. Qubit can be 0, 1 or a combination of 0 and 1, a state called Superposition.
These researchers have created a programmable two-qubit quantum processor , two beryllium ions chilled to just above absolute zero and trapped by a magnetic field on a gold-plated aluminum chip, formed the qubits. Short laser bursts manipulated the beryllium ions to perform the processing operations, while nearby magnesium ions kept the beryllium ions cool and still.
The researchers have estimated 99.99% accurate results and trying to improve the system's fidelity with stronger laser and other refinements. Quantum computing has successfully stepped a move ahead towards large-scale systems through this exciting experiment.
