Computers that can use quantum mechanics’ “spooky” properties to solve problems quicker than existing technology may seem appealing, but they must first overcome a major obstacle. Scientists from Japan may have discovered the solution by demonstrating how a superconducting material, niobium nitride, can be added as a flat, crystalline layer to a nitride-semiconductor substrate. This technique could make it simple to manufacture quantum qubits that can be used with conventional computer devices.
Conventional silicon microprocessor manufacturing techniques have grown over decades and are continually being refined and enhanced. On the other hand, the majority of quantum computing.
Performing computation using quantum-mechanical phenomena such as superposition and entanglement.
