Quantum mechanics explains efficiency of photosynthesis

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis published today in the journal Nature Communications.

Quantum engines must break down

Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The work establishes new laws in the rapidly emerging field of quantum thermodynamics. More...

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
