Electronic generation and detection in nanoelectronic devices at the picosecond scale

A key quantity used to characterise the performance of a quantum device is the ratio between two characteristic times: the time a qubit can survive its quantum properties and the time it takes to complete its operation. Most technologies inherently work at the nanosecond scale. The EU-funded UltraFastNano project will pioneer new concepts at the crossroads between quantum optics and solid-state nanoelectronics. Its aim is to achieve full control of quantum excitations that propagate through the devices on the picosecond scale, about three orders of magnitude faster than other quantum technologies. The project is expected to demonstrate flying qubits, picosecond electronic detectors and picosecond optoelectronic devices.
