Chalmers Researchers Make Bosonic Quantum Operations More Than 1,000 Times Faster

The Quantum InsiderSeptember 10, 20266 min read

Insider Brief PRESS RELEASE — So far, quantum computers have been held back by their extreme sensitivity to errors and external disturbances. The longer a quantum operation takes, the greater the risk that computational errors will occur. Now, researchers at Chalmers University of Technology, in Sweden, have developed a new method that allows a wide […]

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.
