A New, Faster Type of Quantum Computer

 Quantum Computing Concept

Parity computers can perform operations between two or more qubits on a single qubit.

Parity quantum computers make complicated algorithms easier to implement.

In a quantum computer, quantum bits (qubits) act simultaneously as a computing unit and memory. Quantum information cannot be stored in a memory as in a conventional computer since it cannot be copied. Due to this restriction, a quantum computer’s qubits must all be capable of interacting with one another. This continues to be a significant obstacle in the development of powerful quantum computers. In order to overcome this issue, theoretical physicist Wolfgang Lechner, together with Philipp Hauke and Peter Zoller, suggested a novel architecture for a quantum computer in 2015. This architecture is now known as the LHZ architecture after the authors.

“This architecture was originally designed for optimization problems,” recalls Wolfgang Lechner of the Department of Theoretical Physics at the University of Innsbruck, Austria. “In the process, we reduced the architecture to a minimum in order to solve these optimization problems as efficiently as possible.”
