Near perfect mode overlap between independently seeded, gain-switched lasers.

Optics express

Comandar LC, Lucamarini M, Fröhlich B, Dynes JF, Yuan ZL, Shields AJ.
PMID: 27505752
Opt Express. 2016 Aug 08;24(16):17849-59. doi: 10.1364/OE.24.017849.

We drastically improve the mode overlap between independently seeded, gain-switched laser diodes operating at gigahertz repetition rates by implementing a pulsed light seeding technique. Injecting pulsed light reduces the emission time jitter and enables frequency chirp synchronization while maintaining...

Experimental measurement-device-independent quantum digital signatures.

Nature communications

Roberts GL, Lucamarini M, Yuan ZL, Dynes JF, Comandar LC, Sharpe AW, Shields AJ, Curty M, Puthoor IV, Andersson E.

Nat Commun. 2017 Oct 23;8(1):1098. doi: 10.1038/s41467-017-01245-5.

The development of quantum networks will be paramount towards practical and secure telecommunications. These networks will need to sign and distribute information between many parties with information-theoretic security, requiring both quantum digital signatures (QDS) and quantum key distribution (QKD)....

Epitaxial InAs quantum dots grown on GaAs substrate are being used in several applications ranging from quantum communications to solar cells. The growth mechanism of these dots also helps us to explore fundamental aspects of self-organized processes. Here we...

Quantum teleportation of laser-generated photons with an entangled-light-emitting diode.

Nature communications

Stevenson RM, Nilsson J, Bennett AJ, Skiba-Szymanska J, Farrer I, Ritchie DA, Shields AJ.
PMID: 24300834
Nat Commun. 2013;4:2859. doi: 10.1038/ncomms3859.

Quantum teleportation can transfer information between physical systems, which is essential for engineering quantum networks. Of the many technologies being investigated to host quantum bits, photons have obvious advantages as 'pure' quantum information carriers, but their bandwidth and energy...

Pulmonary hypertension attributable to neoplastic emboli: An autopsy study of 20 cases and a review of literature.

Shields DJ, Edwards WD.
PMID: 25990424
Cardiovasc Pathol. 1992 Oct-Dec;1(4):279-87. doi: 10.1016/1054-8807(92)90038-P.

Twenty cases of pulmonary hypertension attributable to neoplastic emboli were the subject of this retrospective autopsy study (1951-1990) at the Mayo Clinic. Fourteen patients were women, and ages ranged from 18 to 82 years (mean 49). In three patients,...

We study the depolarization dynamics of a dense ensemble of dipolar interacting spins, associated with nitrogen-vacancy centers in diamond. We observe anomalously fast, density-dependent, and nonexponential spin relaxation. To explain these observations, we propose a microscopic model where an...

The examination of antibody responses in human immunodeficiency virus (HIV)-1-infected individuals in the setting of antiretroviral treatment (ART) interruption can provide insight into the evolution of antibody responses during viral rebound. In this study, we assessed antibody responses in...

BAER suppression during posterior fossa dural opening.

Surgical neurology international

Shields CB, Shields LB, Jiang YD, Yao T, Zhang YP, Sun DA.

BACKGROUND: Intraoperative monitoring with brainstem auditory evoked responses (BAER) provides an early warning signal of potential neurological injury and may avert tissue damage to the auditory pathway or brainstem. Unexplained loss of the BAER signal in the operating room...

Efficient readout of a single spin state in diamond via spin-to-charge conversion.

Physical review letters

The recent discovery of a large CP violating asymmetry in KL-->pi+pi-e+e- mode has prompted us to seach for the associated KL-->pi 0 pi 0 e+e- decay mode in the KTeV-E799 experiment at Fermilab. In 2.7 x 10(11) K(L) decays,...
