NIST researchers have developed a new method to significantly speed up quantum computing and quantum state preparation using long-range interacting quantum systems. The key innovation is using individual control of all participating quantum bits (qubits) and leveraging long-range interactions to create constructive interference across many interaction pathways.
This approach allows for exponentially faster quantum state transfer and preparation of a wide range of entangled states compared to short-range interaction systems. The potential applications include faster quantum algorithms, entanglement-based magnetometry, and thermometry using defects in diamond.
The research team, led by Alexey V. Gorshkov, includes experts in cybersecurity, information technology, metrology, quantum physics, and quantum processes. The work represents a significant step forward in developing practical quantum technologies.
