Chalmers Researchers Make Bosonic Quantum Operations More Than 1,000 Times Faster
Researchers at Chalmers University of Technology developed a method that can perform a range of operations on bosonic quantum states in a single driving cycle, making some operations more than 1,000 times faster than previous approaches.
The method uses quantum lattice gates and Floquet control to reduce the number of driving cycles needed to manipulate bosonic quantum codes in superconducting quantum circuits.
The researchers say the approach could reduce exposure to errors during quantum operations and support future development of fault-tolerant quantum computing, with experimental demonstrations being discussed at Chalmers.
Spinons may help electrons pair along stripes in some superconductors
Superconductors are materials that carry electricity with zero resistance below specific temperatures. Many of these materials become superconducting at very low temperatures, yet some enter superconducting phases at higher temperatures.
Magic-angle graphene provides evidence for unconventional superconductivity
Researchers have completely suppressed superconductivity in magic-angle graphene by screening interactions between electrons, helping resolve a long-running debate about the origin of the phenomenon.
