Leading-Twist Flavor Singlet Quark TMDs at Small-$x$ Open
We study the small-$x$ asymptotics of the flavor singlet, leading-twist quark Transverse Momentum Dependent parton distribution functions (TMDs). We apply the recently developed Light-Cone Operator Treatment to rewrite the TMD operator def…

Reducing the qubit requirement of Jordan-Wigner encodings of $N$-mode, $K$-fermion systems from $N$ to $\lceil \log_2 {N \choose K} \rceil$ Open
To simulate a fermionic system on a quantum computer, it is necessary to encode the state of the fermions onto qubits. Fermion-to-qubit mappings such as the Jordan-Wigner and Bravyi-Kitaev transformations do this using $N$ qubits to repres…
