Researchers at Princeton University have built a new superconducting qubit with a coherence time three times longer than previously reported in laboratory studies. The underlying technology of transmon qubits is used by Google and IBM as well.
However, the Princeton-developed qubit delivers a coherence time 15 times better than the tech giants, as per the university.
Quantum computers are considered the holy grail of next-generation computing, promising calculations that conventional computers cannot even address. Recent advances in this area have prompted companies to push for commercial applications of this technology. However, many unresolved issues remain to be addressed before quantum computers become mainstream.
When a qubit fails, it can no longer be used for running complex calculations, and the loss of this information can induce errors, further complicating the use of quantum computing.
Princeton’s newly developed qubit addresses this core issue in quantum computing research.
