The trouble is that random noise in the environment can change qubit states during the computation, making the calculation less reliable. Quantum computations are performed by entangling many qubits so that their states are interdependent, then manipulating them according to some algorithm before reading out their final states. Various physical systems can act as qubits, including ions, photons and tiny components made from superconducting material. Quantum computers encode binary information in quantum bits, or qubits, which can take on values of 1, 0 or a superposition of the two. “They all have shortcomings, which means there is lots of room for further work,” he says. “It’s a very exciting time for the field.” Still, Simon cautions that none of the results will transform quantum computing yet. “They are all things we have been waiting a long time to see,” agrees Steven Simon, a theorist at the University of Oxford, UK. The new reports “make a very intriguing advance in quantum computing”, says Jiannis Pachos, a physicist the University of Leeds, UK. Evidence that such quasiparticles may exist has now been reported independently by teams at Google, Microsoft, the quantum-computing firm Quantinuum, and Zhejiang University in China.
But they might, in principle, be tamed by encoding quantum information in a type of quasiparticle called a non-Abelian anyon.
