Supramolecular ‘qudits’ offer a way to power-up quantum computers

Scientists are turning to supramolecular chemistry to design new, more efficient and flexible molecular qubits for quantum technologies, like quantum computing.

‘A qubit is the fundamental unit of quantum information,’ explains Sabine Richert at the University of Freiburg. Unlike classical computers, which use a magnetic material to store and process information as 1s or 0s, quantum computers rely on qubits that can exist in a superposition of two or more quantum states at once. This enables quantum computers to process many possibilities simultaneously, making them better at solving certain problems that would take classical computers years.
