Career Connections: IBM Quantum at NCSU
In this Career Connections talk, hosted at North Carolina State University (NCSU) and online, Dr. Hamed Mohammedbagherpoor is the Technical Lead at IBM Quantum and an instructor at the Electrical and Computer Engineering (ECE) department of NCSU, where he teaches Elements of Control Systems. Having completed his Ph.D. and postdoctoral work at NCSU, Dr. Hamed is well-versed in both academic and industry landscapes. In this talk, he will share his insights on navigating academia, securing internships, and building a career in the tech industry.
QSim Conference Converges for its Second Year at the University of Rhode Island
The conference, notable for its singular focus on quantum simulation, featured talks from leading theoretical and experimental researchers in the field.
Exponentially Reduced Circuit Depths Using Trotter Error Mitigation
Product formulae are a popular class of digital quantum simulation algorithms due to their conceptual simplicity, low overhead, and performance which often exceeds theoretical expectations. Recently, Richardson extrapolation and polynomial interpolation have been proposed to mitigate the Trotter error incurred by use of these formulae. This work provides an improved, rigorous analysis of these techniques for the task of calculating time-evolved expectation values.
Quantum Simulation of Spin-Boson Models with Structure Bath
The spin-boson model, involving spins interacting with a bath of quantum harmonic oscillators, is a widely used representation of open quantum systems that describe many dissipative processes in physical, chemical and biological systems. Trapped ions present an ideal platform for simulating the quantum dynamics of such models, by accessing both the high-quality internal qubit states and the motional modes of the ions for spins and bosons, respectively.

A New Link Between Generalized Quantum Error-Correcting Codes, Complexity and Physics
RQS senior investigator Daniel Gottesman is part of a team of current and former researchers at Perimeter Institute exploring a new universal boundary that separates ‘nontrivial’ quantum error-correction codes from the rest.
Polynomial-Time Classical Simulation of Noisy IQP Circuits with Constant Depth
Sampling from the output distributions of quantum computations comprising only commuting gates, known as instantaneous quantum polynomial (IQP) computations, is believed to be intractable for classical computers, and hence this task has become a leading candidate for testing the capabilities of quantum devices. Here we demonstrate that for an arbitrary IQP circuit undergoing dephasing or depolarizing noise, whose depth is greater than a critical O(1)threshold, the output distribution can be efficiently sampled by a classical computer.
