A mid-circuit erasure check on a dual-rail cavity qubit using the joint-photon number-splitting regime of circuit QED by Stijn J. de Graaf, Sophia H. Xue, Benjamin J. Chapman, James D. Teoh, Takahiro Tsunoda, Patrick Winkel, John W. O. Garmon, Kathleen M. Chang, Luigi Frunzio, Shruti Puri, Robert J. Schoelkopf

“…This ‘joint-photon number-splitting’ regime extends single-oscillator techniques to two-oscillator control, which we use to realize a hardware-efficient erasure check for a dual-rail qubit encoded in two superconducting cavities. This scheme leverages the high-fidelity beamsplitter coupling already required for single- and two-qubit gates while permitting minimal crosstalk between circuit elements. …”

Efficient calculation of self magnetic field, self-force, and self-inductance for electromagnetic coils with rectangular cross-section by Matt Landreman, Siena Hurwitz, Thomas M. Antonsen

“…Also, the magnetic field and its variation inside the conductor is of interest for computing stress and strain, and due to superconducting quench limits. For these force, inductance, energy, and internal field calculations, the coils cannot be naively approximated as infinitesimally thin filaments due to divergences when the source and evaluation points coincide, so more computationally demanding calculations are usually required, resolving the finite cross-section of the conductors. …”

Integrating novel stellarator single-stage optimization algorithms to design the Columbia stellarator experiment by A. Baillod, E.J. Paul, G. Rawlinson, M. Haque, S.W. Freiberger, S. Thapa

“…The Columbia Stellarator eXperiment (CSX), currently being designed at Columbia University, aims to test theoretical predictions related to QA plasma behavior, and to pioneer the construction of an optimized stellarator using three-dimensional, non-insulated high-temperature superconducting (NI-HTS) coils. The magnetic configuration is generated by a combination of two circular planar poloidal field (PF) coils and two 3D-shaped interlinked (IL) coils, with the possibility to add windowpane coils to enhance shaping and experimental flexibility. …”

ASYNCHRONOUS MOTOR WITH A HOLLOW PERFORATED ROTOR by A. N. Annenkov, S. V. Sizikov, A. I. Shiyanov

“…In accordance with the design of the hollow rotor, the bottom of the barrel of one of the ends acts as superconducting short-circulating ring, therefore the ratio of increase in resistance (caused by the transverse edge effect) depends on the distribution of the rotor currents in the area adjacent to the solid frontal portion of the surface of the barrel on end that is opposite to the bottom of the barrel. …”

Sulfur chains glass formed by fast compression by Kaiyuan Shi, Xiao Dong, Zhisheng Zhao, Lei Su, Cheng Ji, Bing Li, Jiaqing Zhang, Xingbang Dong, Pu Qiao, Xin Zhang, Haotian Yang, Guoqiang Yang, Eugene Gregoryanz, Ho-kwang Mao

“…This variability of the starting building blocks is partially responsible for its rich and fascinating phase diagram, with pressure and temperature changing the states of sulfur from insulating molecular rings and chains to semiconducting low- and high-density amorphous configurations to incommensurate superconducting metallic atomic phase. Here, using a fast compression technique, we demonstrate that the rapid pressurisation of liquid sulfur can effectively break the molecular ring structure, forming a glassy polymeric state of pure-chain molecules (Am-S P ). …”

Evidence that transverse variability of critical current density can greatly mitigate screening current stress in high field REBCO magnets by Jeseok Bang, Jonathan Lee, Griffin Bradford, Kwangmin Kim, Xinbo Hu, Dmytro Abraimov, Jan Jaroszynski, Anatolii Polyanskii, So Noguchi, Seungyong Hahn, David C. Larbalestier

“…Abstract Plastic damage of REBCO (REBa2Cu3O7-x, where RE=rare earth) coated conductors by screening current stress (SCS) is a significant concern for ultra-high-field superconducting magnets. Indeed, the third Little Big Coil (LBC3), a REBCO magnet that generated a record, high field of 45.5 T, showed wavy plastic damage produced by excess SCS in all pancakes except two made with single-slit conductors having their slit edges pointing inward towards the magnet center. …”
