Quantum algorithms for scientific discovery

Can we find algorithms to answer open scientific and technological questions in material science, quantum chemistry and nuclear physics?

We work closely with experimental groups on trapped-ion, superconducting, neutral-atom, silicon-dopant and ultracold-gas platforms to turn quantum simulators into tools for answering open questions, from finite-energy phase transitions to the dynamics of driven many-body systems.

Native-particle quantum computing

Can we more efficiently simulate interacting systems consisting of the two fundamental particles in Nature, bosons and fermions, by using quantum computers built from bosons and fermions (in addition to qubits)?

We develop architectures, instruction sets and compilers for hybrid qubit-oscillator and fermionic quantum processors, and the algorithms that run on them.

Near-term fault-tolerant quantum computation

Can we solve interesting problems with a small fault-tolerant quantum computer (1000-10000 physical qubits)?

We design error-correcting codes and fault-tolerant gates tailored to fermionic and Majorana-based hardware, aiming to cut the resources needed for simulating chemistry and materials.
