Measurements at the Quantum Limit (SYQL)
"Measurements at the Quantum Limit" deal with the characterization at the
quantum limit of individual spins, -two level systems, -flux qubits, photons
from x-ray to optical and individual building blocks of large biomolecules in
time of flight experiments. The symposium opens with a special highlight. Dan
Ruger will present pioneering work of the IBM group detecting individual spins
by magnetic force microscopy. Lothar Kador demonstrates spectroscopy of individual
two-level systems. Evgeni Ilichev is characterizing a superconducting flux qubit
deep in the quantum regime with such weak back action on the qubit that a record
value in decoherence time is obtained and entanglement of two such qubits can be
demonstrated. Franz Proebst and Sergei Uchaikin demonstrate in time of flight mass
spectroscopy a kind of sequencing resolution of very large biomolecules. Single
optical quantum detection for cosmology research in astrophysics is introduced by
Ernst Kreysa and utmost energy resolution in x-ray spectroscopy is shown by Andreas
Fleischmann and Jens Hoehne. Prominent tools for the latter achievements are taken
from superconducting electronics.
