By cooling atoms down to near absolute zero and then controlling them with lasers, a company has successfully created a 100-qubit quantum processor that compares to the systems developed by leading quantum players to date. 

ColdQuanta, a US-based company that specializes in the manipulation of cold atoms, unveiled the new quantum processor unit, which will form the basis of the company's 100-qubit gate-based quantum computer, code-named Hilbert, launching later this year after final tuning and optimization work. 

There are various different approaches to quantum computing, and among those that have risen to prominence in the last few years feature superconducting systems, trapped ions, photonic quantum computers and even silicon spin qubits. 

Cold atoms, on the other hand, haven't made waves in the quantum ecosystem so far. ColdQuanta's 100-qubit quantum processor, however, could seemingly compete against the industry's highest standards: for example, IBM's current quantum system, Hummingbird, supports 65 qubits.
