Characterization and quantification of the role of coherence in ultrafast quantum biological experiments using quantum master equations, atomistic simulations, and quantum process tomography
Patrick Rebentrost, Sangwoo Shim, Joel Yuen-Zhou +1
Long-lived electronic coherences in various photosynthetic complexes at cryogenic and room temperature have generated vigorous efforts both in theory and experiment to understand t…
Exciton-phonon information flow in the energy transfer process of photosynthetic complexes
Patrick Rebentrost, Alán Aspuru-Guzik
Non-Markovian and non-equilibrium phonon effects are believed to be key ingredients in the energy transfer in photosynthetic complexes, especially in complexes which exhibit a regi…
Separation of Electromagnetic and Chemical Contributions to Surface-Enhanced Raman Spectra on Nanoengineered Plasmonic Substrates
Semion K. Saikin, Yizhuo Chu, Dmitrij Rappoport +2
Raman signals from molecules adsorbed on a noble metal surface are enhanced by many orders of magnitude due to the plasmon resonances of the substrate. Additionally, the enhanced s…
Simulating chemistry using quantum computers
Ivan Kassal, James D. Whitfield, Alejandro Perdomo-Ortiz +2
The difficulty of simulating quantum systems, well-known to quantum chemists, prompted the idea of quantum computation. One can avoid the steep scaling associated with the exact si…
Simulation of Classical Thermal States on a Quantum Computer: A Transfer Matrix Approach
Man-Hong Yung, Daniel Nagaj, James D. Whitfield +1
We present a hybrid quantum-classical algorithm to simulate thermal states of a classical Hamiltonians on a quantum computer. Our scheme employs a sequence of locally controlled ro…
Discrete single-photon quantum walks with tunable decoherence
M. A. Broome, A. Fedrizzi, B. P. Lanyon +3
Quantum walks have a host of applications, ranging from quantum computing to the simulation of biological systems. We present an intrinsically stable, deterministic implementation…
