We study multilevel fermions in an optical lattice described by the Hubbard model with on site SU(n-symmetric interactions. We show that in an appropriate parameter regime this system can be mapped onto a spin model with all-to-all SU(n-symmetric couplings. Raman pulses that address internal spin states modify the atomic dispersion relation and induce spin-orbit coupling, which can act as a synthetic inhomogeneous magnetic field that competes with the SU(n exchange interactions. We inve...

We introduce a quantum divide and conquer algorithm that enables the use of distributed computing for constrained combinatorial optimization problems. The algorithm consists of three major components: classical partitioning of a target graph into multiple subgraphs, variational optimization over these subgraphs, and a quantum circuit cutting procedure that allows the optimization to take place independently on separate quantum processors. We simulate the execution of the quantum divide and conqu...

We introduce maximum-likelihood fragment tomography (MLFT) as an improved circuit cutting technique for running clustered quantum circuits on quantum devices with a limited number of qubits. In addition to minimizing the classical computing overhead of circuit cutting methods, MLFT finds the most likely probability distribution for the output of a quantum circuit, given the measurement data obtained from the circuit’s fragments. We demonstrate the benefits of MLFT for accurately estimating the o...

We consider the task of performing quantum state tomography on a dstate spin qudit, using only measurements of spin projection onto different quantization axes. By an exact mapping onto the classical problem of signal recovery on the sphere, we prove that full reconstruction of arbitrary qudit states requires a minimal number of measurement axes, r_d^{\mathrm{min}} that is bounded by 2d-1\le r_d^{\mathrm{min}}\le d^2 We conjecture that r_d^{\mathrm{min}}=2d-1 which we verify numerica...

We consider the task of performing quantum state tomography on a dlevel spin qudit, using only measurements of spin projection onto different quantization axes. After introducing a basis of operators closely related to the spherical harmonics, which obey the rotational symmetries of spin qudits, we map our quantum tomography task onto the classical problem of signal recovery on the sphere. We then provide algorithms with O(rd^3)serial runtime, parallelizable down to O(rd^2) for (i) comp...

We investigate many-body spin squeezing dynamics in an XXZ model with interactions that fall off with distance ras 1/r^\alphain D=2and 3spatial dimensions. In stark contrast to the Ising model, we find a broad parameter regime where spin squeezing comparable to the infinite-range \alpha=0limit is achievable even when interactions are short-ranged, \alpha>D A region of ``collective'' behavior in which optimal squeezing grows with system size extends all the way to the $\alpha\to...

We introduce the method of maximum likelihood fragment tomography (MLFT) as an improved circuit cutting technique for running clustered quantum circuits on quantum devices with limited quantum resources. In addition to minimizing the classical computing overhead of circuit cutting methods, MLFT finds the most likely probability distribution over measurement outcomes at the output of a quantum circuit, given the data obtained from running the circuit's fragments. Unlike previous circuit cutting m...
