On quantum scales, there are many second laws of thermodynamics

New research from UCL has uncovered additional second laws of thermodynamics which complement the ordinary second law of thermodynamics, one of the most fundamental laws of nature. These new second laws are generally not noticeable except on very small scales, at which point, they become increasingly important. More...

Quantum Phase Transitions

"Like melting an entire iceberg with a hot poker" – UCL scientists explore the strange world of quantum phase transitions

“What a curious feeling,” says Alice in Lewis Carroll’s tale, as she shrinks to a fraction of her size, and everything around her suddenly looks totally unfamiliar. Scientists too have to get used to these curious feelings when they examine matter on tiny scales and at low temperatures: all the behaviour we are used to seeing around us is turned on its head.

Quantum Computers, when realized, hold the promise of speeding up the solution of certain problems perceived as difficult on a classical computer, and particularly enabling the controlled simulations of the behaviour of complex many-body quantum systems. In the foreseeable future, one expects the size of individual quantum computers to be rather limited due to fundamental obstacles, and identifying viable ways to connect and network such computers to enhance their effective computational power has a high technological incentive.

We have a wide range of research interestsed within the field of quanutm information theory, mostly falling into the following categories:

  • Entanglement and quantum information
  • Quantum Optics
  • Quantum state transfer using spin chains
  • Quantum computation using higher dimensional spins
  • Quantum coherence, correlations and entanglement in photosynthetic complexes
  • Measurement-based quantum computation
  • Quantum many-body systems
  • Quantum thermodynamics
