How psiquantum.com Measures Up

To help you manage your psiquantum.com equity, Prospect has run the company through our machine learning model.

Prospect Rating

3X

Our rating indicates that we believe PsiQuantum could be worth at least three times its current value in four years. For an employee with stock options, this 3x rating signals the potential for a significant return on their equity if the company achieves this growth.

Exit Risk

Moderate Risk

Our moderate risk rating for PsiQuantum is based on its “moonshot” goal to build a utility-scale quantum computer, an ambitious and technically challenging project that increases the risk of the company not reaching a liquidity event for its employees compared to other startups.

Funding Stage

Series E

PsiQuantum's Series E status means it's a mature company with significant financial backing, which often translates to more stability than you'd find at an early-stage startup. You would be joining a well-established player that has already navigated its initial high-risk growth phases.

Company Description

PsiQuantum is a quantum computing company focused on building the world's first useful, fault-tolerant quantum computer. The company's approach is based on photonic qubits, which it manufactures into quantum photonic chips at scale using standard semiconductor processes in partnership with GlobalFoundries. Founded in 2015 by a team of quantum physics and engineering experts—Jeremy O'Brien, Pete Shadbolt, Mark Thompson, and Terry Rudolph—the Palo Alto-based company has grown to over 500 employees. Since its inception as a university spin-out, PsiQuantum has raised significant capital over multiple funding rounds to develop its quantum hardware and a software suite designed for signal processing and algorithm development.

The company aims to deliver a utility-scale quantum computer within this decade, with a focus on scaling its technology to millions of qubits. A key part of this effort is the development of an ultra-high-performance optical switch. Recently, PsiQuantum broke ground on America’s first utility-scale quantum computer facility at the Illinois Quantum and Microelectronics Park in Chicago. The company also introduced its Omega chipset, a manufacturable design for photonic quantum computing, and launched Construct, a software suite for developing fault-tolerant quantum algorithms. Additionally, PsiQuantum has established a research partnership with the U.S. Department of Energy and was selected by DARPA's US2QC program to further develop its technology.
