Researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which could enable the realization of fast and fault-tolerant universal quantum computers.

A quantum computer is a theoretical machine with the potential to solve complex problems much faster than conventional computers. Researchers are currently working on the next step in quantum computing—building a universal quantum computer.

There is still a lot to do. They achieve fidelity values around 90%. For a quantum computer you want something like 99.9% or better, otherwise you are limited to very simple computations our your output will be garbage. I also don't know how well that system scales to more qubits.

One Step Closer to a Universal Quantum Computer.
While it is a fascinating threat to cryptosystems, it is those steps that worry me.
Do they form a circular path, but spiral outwards?
Or is it a random walk, with each step half the length of the last?
Maybe it is a square dance. How many hares, tortoises and millipedes are involved?
