Quantum computing is the next great leap in computing. It promises to make computers exponentially more powerful, potentially opening up new applications in fields including security, medicine, and transportation. Quantum computers use quantum phenomena in addition to electrical circuits to perform tasks that would take conventional computers years to perform. Quantum computing is the next big thing in computing, it promises to be more powerful than today’s computers, but it’s still very much in its infancy.
Quantum computers prove to be more performant than the most evolved supercomputers, despite quantum computing being still in the early phases. Current quantum processors are quite small, and it is believed that much larger processors will be needed to achieve the full potential of quantum computing. A new study reveals a technology that may offer a solution to the problem of scaling up quantum computers.
“Spin-based silicon quantum electronic circuits offer a scalable platform for quantum computation, combining the manufacturability of semiconductor devices with the long coherence times afforded by spins in silicon. Advancing from current few-qubit devices to silicon quantum processors with upward of a million qubits, as required for fault-tolerant operation, presents several unique challenges, one of the most demanding being the ability to deliver microwave signals for large-scale qubit control,” reads the study.
Researchers suggested the use of a three dimensional dielectric resonator to solve this issue. Millions of qubits can be signaled with this method, and only one microwave source is needed for this. There are still many issues with this technology, but it may be up to the challenge of controlling a million qubits before long. Researchers believe they will soon be able to find ways of overcoming the engineering challenges associated with spin-based quantum computers.
