Microwave Spectroscopy of a Carbon Nanotube Charge Qubit
The use of quantum dots to define charge and spin qubits is well established in the field of quantum information processing. Quantum dot charge qubits are attractive because of the possibility of fast qubit control but are sensitive to charge noise which can result in...
Evidence of topological excitations in a quantum magnet
Condensed matter physics is the study of the multitude of ways that matter can organise itself. In each phase as conventionally understood, be it a magnet, metal, superconductor or something else, it is possible to characterise the phase by looking at the system...
LCN collaborates in IARPA-funded QEO program
The Intelligence Advanced Research Projects Activity (IARPA), which sits within the Office of the Director of National Intelligence (ODNI), has just announced that it has embarked on a long-term research effort, involving a multi-institutional collaboration including...
