Quantum computers represent a next step in the fast-paced evolution of technology. Using quantum bits (qubits), they have the potential to run certain calculations exponentially faster than conventional computers. However, developing and fine-tuning quantum computers requires an enormous number of repetitive tests. To accelerate quantum technology development, we need a method that can read quantum states at ultrafast speeds.
