Pushing Quantum Information Across the Channel

  • By Jennifer Zheng
  • 7 December 2021

Congratulations to Vikesh Siddhu for publishing his paper, "Entropic singularities give rise to quantum transmission," in Nature Communications!

The information age is built on efficiently processing digital data. Today this data is processed classically as bits of zeros and ones. But there exists a more powerful kind of information processing. Quantum information, which obeys the laws of quantum mechanics, can not only carry those classic ones and zeros but it can impart them with unbreakable security and process them with computational power that may go beyond the reach of the most powerful supercomputers. . .

 

Local to Meso-scale Order in Electronic Ceramics Characterized by Aberration-Corrected Scanning Transmission Electron Microscopy

Speaker(s): 
Elizabeth Dickey
Dates: 
Friday, December 3, 2021 - 12:15pm

A CMU MSE Seminar

Abstract: The ability to design the composition and microstructure of electronic ceramics for emerging technological applications requires sophisticated characterization techniques that can provide quantitative information about local structure and chemistry. Such structure quantification is particularly important to the fundamental understanding of properties in many important non-linear dielectrics, where chemical heterogeneities associated with dopants or intrinsic lattice defects give rise to local inhomogeneities in charge, strain and...

NSF Grant Will Boost Pitt’s Research Computing Resources

  • By Jennifer Zheng
  • 23 November 2021

A multi-disciplinary team of Pitt researchers has landed a $1.2 million National Science Foundation (NSF) award for new computing resources that will greatly boost the Center for Research Computing’s (CRC) capabilities in speed, power, and scope. Chemistry associate professor Geoffrey Hutchison led the proposal along with associate professors Lillian Chong in chemistry, Inanc Senocak in mechanical engineering and materials science, and David Koes in computational and systems biology. Internal Pitt funding added to the grant creates a total of over $1.5 million for new resources...

Structural Inhomogeneity in Oxide Superconductors

Speaker(s): 
Martin Greven
Dates: 
Wednesday, December 8, 2021 - 4:00pm

Abstract: Superconductivity has been a major research topic for more than a century, yet in many important materials this macroscopic quantum phenomenon remains poorly understood. We have uncovered that superconductivity emerges in an unusual, yet remarkably universal manner upon cooling in three well-known families of complex oxides – strontium titanate, strontium ruthenate, and the cuprates – for which the origin of superconductivity is thought to differ [1]. This breakthrough was enabled by nonlinear magnetic response measurements, an innovative experimental approach...

Quantum Advantage in Optical Laser Communications using NISQ-era Quantum Processors

Speaker(s): 
Kaushik P. Seshadreesan
Dates: 
Friday, December 3, 2021 - 11:00am

A PQI Seminar

Abstract: Optical laser communication forms a cornerstone of modern-day data communications. In the quantum-limited regime of lasercom, where the received optical signal power is small, e.g., in deep-space communications, pre-detection quantum domain collective processing of blocks of received signal pulses corresponding to communication codewords can provide enhanced communication capacity. We present a novel quantum receiver design methodology based on a quantum belief propagation algorithm that attains such enhancement. I will discuss the...

Topological Spintronics

Speaker(s): 
Nitin Samarth
Dates: 
Monday, November 22, 2021 - 3:30pm

A Pitt/CMU Physics Colloquium

Abstract: The past decade has witnessed an explosion of activity in exploring the properties of topological quantum materials whose band structure has interesting features arising from the nexus of topology, spin-orbit coupling, and fundamental symmetries. A key characteristic of the band structure in many of these materials is the ‘spin-momentum correlation’ in helical Dirac states. This leads to the notion of ‘topological spintronics’ devices that seek to exploit efficient spin-charge interconversion for low power, non-...

Continuous Single-Shot Detection of Quasiparticle Trapping

Speaker(s): 
Eli Levenson-Falk
Dates: 
Tuesday, November 16, 2021 - 3:00pm

A Pitt Physics seminar

Register: https://pitt.zoom.us/meeting/register/tJAlcOqgpz4vE9EIq_rfZx-3-ap9ZA4qPK8r

Abstract: Superconducting quantum circuits are plagued by nonequilibrium populations of quasiparticle excitations. These quasiparticles can cause relaxation and spurious excitation of qubit states, producing errors in a quantum algorithm, and can cause correlated errors that are particularly difficult to address with error...
