BASE - The Baryon Antibaryon Symmetry Experiment
C. Smorra, K. Blaum, L. Bojtar +17
The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing the magnetic moment…
A reservoir trap for antiprotons
Christian Smorra, Andreas Mooser, Kurt Franke +10
We have developed techniques to extract arbitrary fractions of antiprotons from an accumulated reservoir, and to inject them into a Penning-trap system for high-precision measureme…
Direct high-precision measurement of the magnetic moment of the proton
A. Mooser, S. Ulmer, K. Blaum +7
The spin-magnetic moment of the proton is a fundamental property of this particle. So far has only been measured indirectly, analysing the spectrum of an atomic hydroge…
The magnetic moments of the proton and the antiproton
S. Ulmer, A. Mooser, K. Blaum +14
Recent exciting progress in the preparation and manipulation of the motional quantum states of a single trapped proton enabled the first direct detection of the particle's spin sta…
Towards a high-precision measurement of the antiproton magnetic moment
C. Smorra, K. Blaum, K. Franke +10
The recent observation of single spins flips with a single proton in a Penning trap opens the way to measure the proton magnetic moment with high precision. Based on this success,…
Demonstration of the Double Penning Trap Technique with a Single Proton
A. Mooser, S. Braeuninger, K. Franke +12
Spin flips of a single proton were driven in a Penning trap with a homogeneous magnetic field. For the spin-state analysis the proton was transported into a second Penning trap wit…
Resolution of Single Spin-Flips of a Single Proton
A. Mooser, H. Kracke, K. Blaum +7
The spin magnetic moment of a single proton in a cryogenic Penning trap was coupled to the particle's axial motion with a superimposed magnetic bottle. Jumps in the oscillation fre…
Exploiting boundary states of imperfect spin chains for high-fidelity state transfer
M. Bruderer, K. Franke, S. Ragg +2
We study transfer of a quantum state through XX spin chains with static imperfections. We combine the two standard approaches for state transfer based on (i) modulated couplings be…
Noninvasiveness and time symmetry of weak measurements
Adam Bednorz, Kurt Franke, Wolfgang Belzig
Measurements in classical and quantum physics are described in fundamentally different ways. Nevertheless, one can formally define similar measurement procedures with respect to th…
