Quantum computing is one of the most exciting and experimental tech industries. It actually uses subatomic particles, like electrons and photons, and combines it with quantum mechanics. This allows the computer to use "qubits" to be in two states at once. The final result is that quantum computers should be able to handle calculations much faster than traditional computers.

Today, the Boston-based QuEra Computing company, the makers of its own neutral-atom quantum computer called Aquila, revealed a new encoding method breakthrough that it says will allow its computer to handle more applications.

QuEra describes the previous limitations for its quantum computer:
"Specifically, the native connectivity of the qubits for a given platform often restricts the class of problems that can be addressed. For instance, Rydberg atom arrays naturally allow solving for maximum independent set (MIS) problems, but native encodings are restricted to so-called unit-disk graphs."

However, thanks to this new encoding method, QuEra says its quantum computer can overcome those restrictions:
"Now, new classes of optimization problems can be solved by neutral-atom machines. These include maximum independent sets on graphs with arbitrary connectivity, and quadratic unconstrained binary optimization (QUBO) problems with arbitrary or restricted connectivity."
