Error sources in heralded quantum Zeno gates

Nodurft, I.C.; Franson, J.D. (2021-05-28)

Quantum logic gates for photonic qubits can be implemented using the quantum Zeno effect based on strong two-photon absorption. The fidelity of quantum Zeno gates of this kind may be substantially reduced by photon loss. ...

Quantum Heat Engines with Singular Interactions

Myers, Nathan; McCready, Jacob; Deffner, Sebastian (MDPI, 2021-05-31)

By harnessing quantum phenomena, quantum devices have the potential to outperform their classical counterparts. Here, we examine using wave function symmetry as a resource to enhance the performance of a quantum Otto engine. ...

We present and perform a detailed analysis of multi-wavelength observations of \thisgrb, an optical bright GRB with an observed reverse shock (RS) signature. Observations of this GRB were acquired with the BOOTES-4 robotic ...

Structural basis for zinc-induced activation of a zinc uptake transcriptional regulator

Liu, Fenmei; Su, Zihui; Chen, Peng; Tian, Xiaolin; Wu, Lijie; Tang, Dong-Jie; Li, Peifang; Deng, Haiteng; Ding, Pengfei; Fu, Qiang; Tang, Ji-Liang; Ming, Zhenhua (Oxford University Press, 2021-05-28)

The zinc uptake regulator (Zur) is a member of the Fur (ferric uptake regulator) family transcriptional regulators that plays important roles in zinc homeostasis and virulence of bacteria. Upon zinc perception, Zur binds ...

Robust photon-mediated entangling gates between quantum dot spin qubits

Warren, Ada; Güngördü, Utkan; Kestner, J. P.; Barnes, Edwin; Economou, Sophia E. (2021-01-27)

Significant experimental advances in single-electron silicon spin qubits have opened the possibility of realizing long-range entangling gates mediated by microwave photons. Recently proposed iSWAP gates, however, require ...

Single-tone pulse sequences and robust two-tone shaped pulses for three spin qubits with always-on exchange

Kanaar, David W.; Wolin, Sidney; Güngördü, Utkan; Kestner, J. P. (2021-01-21)

Quantum computation requires high-fidelity single-qubit and two-qubit gates on a scalable platform. Silicon spin qubits are a promising platform toward realization of this goal. In this paper we show how to perform ...

sxtA4+ and sxtA4- Genotypes Occur Together within Natural Pyrodinium bahamense Sub-Populations from the Western Atlantic

Cusick, Kathleen; Duran, Gabriel (MDPI, 2021-05-23)

Saxitoxin (STX) is a secondary metabolite and potent neurotoxin produced by several genera of harmful algal bloom (HAB) marine dinoflagellates. The basis for variability in STX production within natural bloom populations ...

First data on aquaculture of the Tripletail, Lobotes surinamensis, a promising candidate species for U.S. marine aquaculture

Saillant, Eric; Adams, Nicholas; Lemus, Jason T.; Franks, James S.; Zohar, Yonathan; Stubblefield, John; Manley, Christopher (Wiley Online Library, 2021-05-18)

The Tripletail, Lobotes surinamensis, is a warm-water pelagic fish that is increasingly targeted by U.S. anglers. The superior quality of Tripletail flesh coupled with the lack of domestic commercial fisheries stimulated ...

Race and other sociodemographic categories are differentially linked to multiple dimensions of interpersonal-level discrimination: Implications for intersectional, health research

We present an in-depth analysis of the spectral and temporal behavior of a long almost uninterrupted INTEGRAL observation of Vela X-1 in Nov/Dec 2003. In addition to an already high activity level, Vela X-1 exhibited ...

Whole transcriptome analysis reveals changes in expression of immune-related genes during and after bleaching in a reef-building coral

Pinzón, Jorge H.; Kamel, Bishoy; Burge, Colleen A.; Harvell, C. Drew; Medina, Mónica; Weil, Ernesto; Mydlarz, Laura D. (The Royal Society, 2015-04-01)

Climate change is negatively affecting the stability of natural ecosystems, especially coral reefs. The dissociation of the symbiosis between reef-building corals and their algal symbiont, or coral bleaching, has been ...
