In Person & Virtual

In “Quantum Steampunk”, the exciting new book from Harvard physicist Dr. Nicole Yunger Halpern, the industrial revolution meets the quantum-technology revolution. While readers follow the adventures of a rag-tag steampunk crew on trains, dirigibles, and automobiles, they explore questions such as, “Can quantum physics revolutionize engines?” and “What deeper secrets can quantum information reveal about the trajectory of time?” Join Dr.

Dequantizing the Quantum Singular Value Transformation: Hardness and Applications to Quantum Chemistry and the Quantum PCP Conjecture

Sevag Gharibian, Paderborn University

The Quantum Singular Value Transformation (QSVT) is a recent technique that gives a unified framework to describe most quantum algorithms discovered so far, and may lead to the development of novel quantum algorithms. In this paper we investigate the hardness of classically simulating the QSVT.

Ultrafast single photon optical gating via the Kerr effect

In optical quantum communication and information protocols, it is important to have access to a high dimensional Hilbert space. The energy-time degree of freedom of photons may be used to access such a Hilbert space, as long as accurate measures of frequency and time of single photons are possible. With ultrafast timescales, it is known how to measure the phase of an electric field as a function of time, but new techniques are required for the low power, single photon regime.

Quantum Linear Solvers and Their Applications

I will talk about the quantum algorithms developed by block-encoding techniques for solving linear system of equations. We will see what sorts of speed-ups have been proved or could be expected, while exploiting a quantum linear solver as a subroutine, for tasks ranging from solving PDEs to sampling from Gibbs distributions.

Xiao Mi, Google

A fertile ground of exploration for NISQ quantum computers is the study of quantum phases and their associated transitions into chaotic regimes. Sharp growths of quantum correlation and entanglement often accompany quantum phases near their critical points, providing opportunities for quantum computational advantage. Furthermore, the discovery of any robust quantum order in, for example, topological phases of matter may also enable new error-correction paradigms. I will present two recent experiments studying quantum phases of matter with superconducting qubits.

The possibility for quantum computers to outcompete classical high-performance computers at their own game looms tantalizingly on the horizon. The main obstacle to performing large-scale computations remains the cascade of small inaccuracies on individual components throughout large quantum circuits. Since the 1990s, techniques have been invented for suppressing these errors, principally within academia.

Communication networks are an essential part of our world today, used in transactions from banking to education, global business exchanges to defence. What happens when our private information is no longer private? Powerful quantum computers will have the ability to crack the encryption of public keys that we currently use to secure our data, putting our privacy at risk.

Bhaskaran Muralidharan - Department of Electrical Engineering, Indian Institute of Technology Bombay, India

Semiconductor nanowire-superconductor hybrid systems provide a promising platform for hosting Majorana zero modes. However, the conclusive experimental detection of these exotic modes is a much debated and contentious issue. In this talk, we will describe conductance spectroscopy measurements and the current experimental status on their detection.
