Career Connections: Lightsynq at Princeton University
In this Career Connections talk, Dr. Mihir Bhaskar (CEO and Co-Founder of Lightsynq) will share insights from his career journey: first building a science experiment in the lab as a PhD student, then moving to AWS to launch a new R&D initiative, and finally starting a quantum technology company to build a product. He will also talk about the integrated photonic capabilities his team has developed along the way, and how he thinks they can solve key bottlenecks in quantum information technology.
Parallel-sequential circuits for quantum state preparation
We introduce parallel-sequential (PS) circuits, a family of quantum circuits characterized by a tunable degree of entanglement and maximum correlation length, which interpolates between brickwall and sequential circuits. We provide evidence that on noisy devices, properly chosen PS circuits suppress error proliferation and exhibit superior trainability and evaluation accuracy when employed as variational circuits, thus outperforming brickwall, sequential, and log-depth circuits in [Malz*, Styliaris*, Wei*, Cirac, PRL 2024] across most parameter regimes.
Optimal Quantum Computing Architecture through Deep Co-Design
Much like classical computing, quantum computers follow an abstraction model for their architecture. The performance of a quantum computer is dependent on the performance of each layer of this abstraction model, as well as the model itself. Due to its centrality in the quantum computing stack, the control system (consisting of hardware, firmware, and software) plays a strategically outsized role in the problem of quantum architecture.
Quantum algorithms (CMSC858Q, Spring 2025)

An introduction to the concept of a quantum computer, including algorithms that outperform classical computation and methods for performing quantum computation reliably in the presence of noise. As this is a multidisciplinary subject, the course will cover basic concepts in theoretical computer science and physics in addition to introducing core quantum computing topics.
Parallel-sequential circuits for quantum state preparation
Abstract: We introduce parallel-sequential (PS) circuits, a family of quantum circuits characterized by a tunable degree of entanglement and maximum correlation length, which interpolates between brickwall and sequential circuits. We provide evidence that on noisy devices, properly chosen PS circuits suppress error proliferation and exhibit superior trainability and evaluation accuracy when employed as variational circuits, thus outperforming brickwall, sequential, and log-depth circuits in [Malz*, Styliaris*, Wei*, Cirac, PRL 2024] across most parameter regimes.
Enhancing the Performance of Optical Lattice Clocks with Multiple Atomic Ensembles
The remarkable precision of optical atomic clocks enables new applications and offers sensitivity to novel and exotic physics. In this talk I will explain the motivation and operating principles of a multiplexed strontium optical lattice clock, which consists of two or more atomic ensembles of trapped, ultra-cold strontium in one vacuum chamber. This miniature clock network enables us to bypass the primary limitations to atomic clock comparisons and achieve new levels of precision.
