These materials function as tunable qubits that preserve spin states at room temperature, improving standard quantum computing systems. Quantum computers have the potential to perform simulations and make calculations infeasibly intensive or complex for classical computers. Quantum information science can help develop new medications, better machine learning, more secure encryption, and more realistic simulations for cutting-edge scientific research. However, available quantum systems store quantum information using qubit material that must remain cooled to absolute zero, and the information is only accessible using magnetic techniques. This makes developing useful quantum computers difficult.
Researchers at the University of Florida and Universidad de los Andes have developed metal-organic nanoparticle matrix qubit materials that store quantum data at room temperature and enable easier access to the data via electrical charge. These materials facilitate more practical quantum systems with greater accessibility, scalability, and functionality.
More practical quantum computing systems using enhanced qubit materials that work at room temperature
The material consists of multiferroic bismuth iron oxide (BFO) nanoparticles embedded in a metal-organic matrix. It has a unique combination of properties that makes it fit for use as a qubit in tunable quantum spin systems. The material conserves quantum spin states at room temperature and allows control of those states using charge currents due to its enhanced magnetoelectric coupling. Varying the geometric and chemical characteristics of the material can optimize the spin coherence time for a given quantum system.
