Nonlinear quantum evolution of a dissipative superconducting qubit
Orion Lee, Qian Cao, Yogesh N. Joglekar +1
Unitary and dissipative models of quantum dynamics are linear maps on the space of states or density matrices. This linearity encodes the superposition principle, a key feature of…
Search for Axion Dark Matter from 1.1 to 1.3 GHz with ADMX
ADMX Collaboration, G. Carosi, C. Cisneros +50
Axion dark matter can satisfy the conditions needed to account for all of the dark matter and solve the strong CP problem. The Axion Dark Matter eXperiment (ADMX) is a direct dark…
Exploring the topology of a non-Hermitian superconducting qubit using shortcuts to adiabaticity
Serra Erdamar, Maryam Abbasi, Weijian Chen +3
Open quantum systems described by a non-Hermitian Hamiltonian exhibit rich dynamics due to the topology of their complex energy spectrum. By encircling an exceptional point degener…
Axion Dark Matter eXperiment around 3.3 μeV with Dine-Fischler-Srednicki-Zhitnitsky Discovery Ability
C. Goodman, M. Guzzetti, C. Hanretty +46
We report the results of a QCD axion dark matter search with discovery ability for Dine Fischler Srednicki Zhitnitsky (DFSZ) axions using an axion haloscope. Sub-Kelvin noise tempe…
Improved Receiver Noise Calibration for ADMX Axion Search: 4.54 to 5.41 eV
M. Guzzetti, D. Zhang, C. Goodman +48
Axions are a well-motivated candidate for dark matter. The preeminent method to search for axion dark matter is known as the axion haloscope, which makes use of the conversion of a…
Exploring the Accuracy of Interferometric Quantum Measurements under Conservation Laws
Nicolò Piccione, Maria Maffei, Andrew N. Jordan +2
A (target) quantum system is often measured through observations performed on a second (meter) system to which the target is coupled. In the presence of global conservation laws ho…
