PsiQuantum
In this talk we will describe progress towards large-scale, fault-tolerant quantum computing with photons. This talk will span materials innovations for high-performance photonics, improvements in photonic component performance with an emphasis on improved optical loss, prototype systems of entangled photonic qubits, qubit networking, and novel high-power cryogenic cooling solutions designed for future datacenter-scale quantum computers. We will show new prototype systems designed to progressively overcome the key challenges to scaling up photonic quantum computers. We will also give an overview of the architecture of fusion-based photonic quantum computers, describe near-term systems milestones, and give a view on the long-term roadmap to useful, fault-tolerant machines.

Towards an On-chip Ti:sapphire Mode-Locked Laser
View Info
Hide Info
Ultrashort pulsed (mode-locked) lasers are widely used for many applications, such as imaging, biosensing, spectroscopy, LiDARs, and communication. Pulsed lasers are also important in quantum sciences, where they are used for precise control and measurement of quantum systems. Because of the wide variety of applications, femtosecond pulse technology has already led to four Nobel Prizes (1999, 2005, 2018, 2023). However, state-of-the-art femtosecond lasers are bulky and cost hundreds of thousands of dollars, remarkably limiting their use. Our goal is to fabricate such ultrashort lasers on an integrated photonic platform, bringing the cost and size down by several orders of magnitude and democratizing the femtosecond technology for even wider use.
In this talk, I present our lab group’s work on miniaturizing Ti:sapphire laser technology, a gold standard platform for tunable and ultrashort (5-10 fs) lasers due to their unmatched bandwidth (650-1100 nm). So far, we have demonstrated on-chip tunable Ti:sapphire lasers less than 0.5 mm in size, enabling optical control of silicon carbide defects in a cavity QED experiment. Now, we focus on mode-locking on-chip Ti:sapphire lasers, working towards the first on-chip femtosecond laser using a solid-state crystal gain material.

Point defects in diamond have emerged as powerful tools for quantum technologies owing to their excellent optical and spin properties. These defects serve as deterministic single-photon sources and solid-state quantum memories for quantum information processing as well as nanoscale quantum sensors to detect various physical quantities (e.g., magnetic fields, electric fields, and temperature). Recent development of nanofabrication technologies for high-quality single-crystal diamond has boost the diamond-based quantum technologies. Incorporating these diamond nanostructures with mature integrated photonics would further accelerate building scalable and practical quantum systems. This talk will focus on recent progress and challenges in hybrid diamond integrated photonics.

Electro-Optic Co-Design for High Baudrate Communication
View Info
Hide Info
As the demand for high-baudrate communication continues to rise, opto-electronic co-design is becoming ever more essential. Applications such as high-speed optical interconnects and radio-over-fiber require precise coordination of key performance parameters, such as noise, bandwidth, and linearity, across both photonic integrated circuits (PICs) and electronic integrated circuits (EICs). However, the absence of a mature PIC design flow remains a significant bottleneck, especially as system complexity scales. This work introduces a PIC design flow, mirroring many aspects of EIC design practices, implemented within the Cadence environment. Specifically, it presents the electro-optic design of a traveling-wave Mach-Zehnder modulator (TW-MZM), alongside the design of a photonics-assisted phased array.

RoQNET - Rochester Quantum Photonic Integrated Circuit (PIC) Network
View Info
Hide Info
Photonic integrated circuits (PICs) are poised to play a transformative role in the development of large-scale, heterogeneous quantum networks by providing compact, stable, and manufacturable platforms for generating, manipulating, and transmitting quantum states of light. Within the Rochester Quantum Network (RoQNET)—a 38 km metro optical fiber testbed between the University of Rochester and Rochester Institute of Technology—we have shown how small-scale chips can support high-performance quantum information processing. By integrating photon-pair sources, reconfigurable circuitry, and wavelength-bridging devices onto PICs, we are building systems that connect diverse quantum nodes. Ultimately, these integrated photonic technologies chart a path toward quantum networks enabling secure communication, distributed entanglement, and scalable quantum information processing.

Q4S: Entanglement Swapping for Deployment in Low-Earth Orbit
View Info
Hide Info
Quantum repeaters are a necessary building block of a distributed quantum network. A key protocol for quantum repeaters is entanglement swapping, which is used to entangle two independent photons that have never interacted. In the most common implementation, two pairs of photons are created and a joint measurement of two of the photons (one from each pair) projects the remaining two photons onto an entangled state. Previous demonstrations of entanglement swapping have required large, power-hungry components and operate in tightly controlled laboratory environments. The goal of the Q4S mission is to overcome these constraints to perform entanglement swapping onboard a satellite. Q4S employs low size, weight, and power components, operates over a wide ambient temperature range, and is robust to certain single point failures, enabling entanglement swapping to be carried out in a deployable satellite. Here we present design choices and preliminary performance results of the prototype ground-twin. This work is an important step towards deploying a satellite quantum network for long-distance entanglement distribution.
