Caltech and start-up Oratomic researchers have developed an error-correction method for neutral atom quantum computers that could enable fault-tolerant machines with just 10,000–20,000 qubits, far ...

The idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of ...

Physicists in China have simulated false vacuum decay, a rare quantum process theorized as a possible—though extremely unlikely—way the universe could abruptly end. Using a ring of Rydberg atoms and ...
