Yale University researchers have developed a technique for saving Schrodinger's cat, which symbolizes quantum superposition and unpredictability, by predicting its jumps and taking real-time actions.
With this development, scientists can establish an early-warning system for imminent jumps of artificial atoms housing quantum data.
A quantum jump is the sudden switch between two discrete energy states; coping with the jumps of quantum bits (qubits), or incarnate errors in calculations every time a qubit is measured, is required for quantum computing.
The Yale researchers indirectly observed a superconducting artificial atom in a three-dimensional aluminum cavity, using microwave generators to irradiate the atom, inducing quantum jumps.
Real-time monitoring allowed the researchers to note the sudden absence of detection photons, signaling imminent jumps.
