Identifying Stabilizer States
Daniel Gottesman - University of Maryland, College Park
Suppose you are given m copies of an unknown n-qubit stabilizer state. How many copies do you need before you can figure out exactly what state it is? Just to specify the state requires about n^2/2 bits, so certainly m is at least n/2. Using only single-copy measurements, we show how to identify the…
Tomography without trusted apparatus
Michele Mosca - Institute for Quantum Computing (IQC)
I will talk about \'self-testing\' quantum apparatus.
News Flash: adapting compressed sensing to quantum systems
Robert Kosut - SC Solutions (United States)
Priors for quantum states & processes
Karol Zyczkowski - Jagiellonian University
As became apparent during Koenraad\'s talk, there are some important subleties to concepts like \'flat prior\' and \'uniform distribution\'... especially over probability simplices and quantum state spaces. This is a key problem for Bayesian approaches. Perhaps we\'re more interested in Jeffreys…
Dynamical Evolution of Superoperator for Hamiltonian Identification and Quantum Dynamical Control
Estimation of quantum Hamiltonian systems is a pivotal challenge to modern quantum physics and especially plays a key role in quantum control. In the last decade, several methods have been developed for complete characterization of a \'superopertor\', which contains all information about a quantum…
Polarisation tomography of macro- and mesoscopic quantum states of light
Maria Chekhova - Max Planck Institute for the Science of Light
We report an experiment on reconstructing the quantum state of bright (macroscopic) polarization-squeezed light generated in a birefringent (polarization-maintaining) fibre due to the Kerr nonlinearity. The nonlinearity acts on both H and V polarization components, producing quadrature squeezing; by…
Learning from experiments on coherent control
David Cory - Institute for Quantum Computing (IQC)
I will discuss a few case studies of coherent control experiments and how we use quantum esstimation to motivate improved experiments. Examples from NMR with physical and logical quits, electron/nuclear spin systems and persistent current flux qubits
