Bosonic Error Correction with Fluxonium
Shantanu R. Jha, Shoumik D. Chowdhury, Gabriele Rolleri +22
Bosonic quantum error correction (QEC) offers a hardware-efficient route to fault-tolerant quantum computing. To date, however, superconducting circuit implementations of bosonic c…
Quantum Monte Carlo for Gauge Fields and Matter without the Fermion Determinant
Debasish Banerjee, Emilie Huffman
Ab-initio Monte Carlo simulations of strongly-interacting fermionic systems are plagued by the fermion sign problem, making the non-perturbative study of many interesting regimes o…
Uncovering conformal symmetry in the Ising transition: State-operator correspondence from a fuzzy sphere regularization
Wei Zhu, Chao Han, Emilie Huffman +2
The Ising transition, the most celebrated and unsolved critical phenomenon in nature, has long been conjectured to have emergent conformal symmetry, similar to the case of the…
Exploring Bosonic and Fermionic Link Models on d tubes
Debasish Banerjee, Emilie Huffman, Lukas Rammelmüller
Quantum link models (QLMs) have attracted a lot of attention in recent times as a generalization of Wilson's lattice gauge theories (LGT), and are particularly suitable for realiza…
Critical exponents for a spin-charge flip symmetric fixed point in 2+1d with massless Dirac fermions
Emilie Huffman
In the Hamiltonian picture, free spin- Dirac fermions on a bipartite lattice have an (spin-charge) symmetry. Here we construct an interacting lattice model with an inte…
Introducing Fermionic Link Models
Debasish Banerjee, Emilie Huffman, Lukas Rammelmüller
Quantum link models (QLMs) are extensions of Wilson-type lattice gauge theories, and show rich physics beyond the phenomena of conventional Wilson gauge theories. Here we explore t…

Emilie Huffman, Miguel García Vera, Debasish Banerjee
Practical quantum computing holds clear promise in addressing problems not generally tractable with classical simulation techniques, and some key physically interesting application…
Quantum Criticality of Anti-ferromagnetism and Superconductivity with Relativity
Hanqing Liu, Emilie Huffman, Shailesh Chandrasekharan +1
We study a quantum phase transition from a massless to massive Dirac fermion phase in a new two-dimensional bipartite lattice model of electrons that is amenable to sign-free quant…
Fermion Bag Approach for Hamiltonian Lattice Field Theories
Emilie Huffman
Two formidable bottlenecks to the applicability of QMC include: (1) the sign problem and (2) algorithmic update inefficiencies. In this thesis, I overcome both these difficulties f…
Fermion-bag inspired Hamiltonian lattice field theory for fermionic quantum criticality
Emilie Huffman, Shailesh Chandrasekharan
Motivated by the fermion bag approach we construct a new class of Hamiltonian lattice field theories that can help us to study fermionic quantum critical points, particularly those…

Leggett-Garg test of superconducting qubit addressing the clumsiness loophole
Emilie Huffman, Ari Mizel
The Leggett-Garg inequality holds for any macrorealistic system that is being measured noninvasively. A violation of the inequality can signal that a system does not conform to our…
