Job Description

PsiQuantum offers a quantum algorithms and compilation internship for postgraduate students and recent graduates, based in Palo Alto, California or remote. Interns work on algorithms for fault-tolerant quantum computers, from optimising common subroutines to compiling them into logical gates and estimating the resources they need.

At a glance

  • Role: Intern, Quantum Algorithms and Compilation
  • Where: Palo Alto, California, or remote
  • Who: postgraduate students or recent postgraduates
  • Focus: fault-tolerant algorithms, compilation and resource estimation
  • Apply: open until filled (re-checked 11 October 2026)

About the quantum algorithms internship

  • Develop quantum algorithms for impactful problems
  • Optimise common subroutines used in fault-tolerant quantum algorithms
  • Compile quantum algorithms to logical gate sets
  • Build in optimisations that take the hardware architecture into account
  • Estimate the quantum resources algorithms need

PsiQuantum builds its quantum computers from photons on silicon chips. Photonic qubits are naturally suited to networking and to fusion-based quantum computing, but they need error-correction schemes and algorithms designed around photon loss and the architecture’s building blocks, which is the kind of problem these roles work on.

What PsiQuantum is looking for

  • Currently studying for, or having completed, a postgraduate degree related to quantum algorithms, circuit compilation, fault tolerance or another area of quantum computing
  • Programming experience, for example Python, and collaborative tools such as Git
  • A creative, adaptable approach to problems and the ability to work in a highly collaborative team

Pay and location

The internship can be based in Palo Alto, California, or done remotely. PsiQuantum’s posting lists pay for some locations; check it for the rate that applies to you.

How to apply

Apply through the official PsiQuantum job posting. PsiQuantum’s posting does not give a closing date, so the role is open until filled; ResearchJobs.in will re-check this listing on 11 October 2026. Check the posting for location and work-authorisation details before you apply.

How to prepare for this application

  • Subroutines: revise the building blocks of fault-tolerant algorithms, such as arithmetic circuits, state preparation, block encodings and phase estimation.
  • Compilation: know how a circuit is compiled into Clifford+T gates and why T gates dominate the cost.
  • A small project: implement and cost a toy algorithm in Python and bring the notebook to discuss.
  • Git hygiene: a tidy public repository is a strong signal for software-heavy research internships.
  • Your thesis: explain in two minutes how your postgraduate work connects to fault tolerance.

About PsiQuantum

PsiQuantum was founded in 2016 with a single aim: to build and deploy million-qubit, fault-tolerant quantum computers. Its architecture is based on silicon photonics, using high-volume semiconductor manufacturing, including partners such as GlobalFoundries, to make the photonic chips its machines are built from.
