text: The generation of optically broadband Nyquist pulse sequences using an integrated
Mach-Zehnder modulator (MZM) in a thin-film lithium-niobate (TFLN) platform with
repetition rates of 5 to 32 GHz and optical bandwidths of up to 160 GHz is demonstrated.
Nyquist pulse sequences with high optical bandwidth can be used as synchronization
and control signals in quantum sources based on photon pair generation.

text: "Understanding the entanglement structure of local Hamiltonian ground spaces\r\nis
a physically motivated problem, with applications ranging from tensor\r\nnetwork
design to quantum error-correcting codes. To this end, we study the\r\ncomplexity
of estimating ground state entanglement, and more generally entropy\r\nestimation
for low energy states and Gibbs states. We find, in particular, that\r\nthe classes
qq-QAM [Kobayashi, le Gall, Nishimura, SICOMP 2019] (a quantum\r\nanalogue of
public-coin AM) and QMA(2) (QMA with unentangled proofs) play a\r\ncrucial role
for such problems, showing: (1) Detecting a high-entanglement\r\nground state
is qq-QAM-complete, (2) computing an additive error approximation\r\nto the Helmholtz
free energy (equivalently, a multiplicative error\r\napproximation to the partition
function) is in qq-QAM, (3) detecting a\r\nlow-entanglement ground state is QMA(2)-hard,
and (4) detecting low energy\r\nstates which are close to product states can range
from QMA-complete to\r\nQMA(2)-complete. Our results make progress on an open
question of [Bravyi,\r\nChowdhury, Gosset and Wocjan, Nature Physics 2022] on
free energy, and yield\r\nthe first QMA(2)-complete Hamiltonian problem using
local Hamiltonians (cf. the\r\nsparse QMA(2)-complete Hamiltonian problem of [Chailloux,
Sattath, CCC 2012])."

text: "Despite the fundamental role the Quantum Satisfiability (QSAT) problem has\r\nplayed
in quantum complexity theory, a central question remains open: At which\r\nlocal
dimension does the complexity of QSAT transition from \"easy\" to \"hard\"?\r\nHere,
we study QSAT with each constraint acting on a $k$-dimensional and\r\n$l$-dimensional
qudit pair, denoted $(k,l)$-QSAT. Our first main result shows\r\nthat, surprisingly,
QSAT on qubits can remain $\\mathsf{QMA}_1$-hard, in that\r\n$(2,5)$-QSAT is $\\mathsf{QMA}_1$-complete.
In contrast, $2$-SAT on qubits is\r\nwell-known to be poly-time solvable [Bravyi,
2006]. Our second main result\r\nproves that $(3,d)$-QSAT on the 1D line with
$d\\in O(1)$ is also\r\n$\\mathsf{QMA}_1$-hard. Finally, we initiate the study
of 1D $(2,d)$-QSAT by\r\ngiving a frustration-free 1D Hamiltonian with a unique,
entangled ground state.\r\n Our first result uses a direct embedding, combining
a novel clock\r\nconstruction with the 2D circuit-to-Hamiltonian construction
of [Gosset, Nagaj,\r\n2013]. Of note is a new simplified and analytic proof for
the latter (as\r\nopposed to a partially numeric proof in [GN13]). This exploits
Unitary Labelled\r\nGraphs [Bausch, Cubitt, Ozols, 2017] together with a new \"Nullspace
Connection\r\nLemma\", allowing us to break low energy analyses into small patches
of\r\nprojectors, and to improve the soundness analysis of [GN13] from\r\n$\\Omega(1/T^6)$
to $\\Omega(1/T^2)$, for $T$ the number of gates. Our second\r\nresult goes via
black-box reduction: Given an arbitrary 1D Hamiltonian $H$ on\r\n$d'$-dimensional
qudits, we show how to embed it into an effective null-space\r\nof a 1D $(3,d)$-QSAT
instance, for $d\\in O(1)$. Our approach may be viewed as a\r\nweaker notion of
\"simulation\" (\\`a la [Bravyi, Hastings 2017], [Cubitt,\r\nMontanaro, Piddock
2018]). As far as we are aware, this gives the first\r\n\"black-box simulation\"-based
$\\mathsf{QMA}_1$-hardness result, i.e. for\r\nfrustration-free Hamiltonians."

text: "Estimating ground state energies of many-body Hamiltonians is a central task\r\nin
many areas of quantum physics. In this work, we give quantum algorithms\r\nwhich,
given any $k$-body Hamiltonian $H$, compute an estimate for the ground\r\nstate
energy and prepare a quantum state achieving said energy, respectively.\r\nSpecifically,
for any $\\varepsilon>0$, our algorithms return, with high\r\nprobability, an
estimate of the ground state energy of $H$ within additive\r\nerror $\\varepsilon
M$, or a quantum state with the corresponding energy. Here,\r\n$M$ is the total
strength of all interaction terms, which in general is\r\nextensive in the system
size. Our approach makes no assumptions about the\r\ngeometry or spatial locality
of interaction terms of the input Hamiltonian and\r\nthus handles even long-range
or all-to-all interactions, such as in quantum\r\nchemistry, where lattice-based
techniques break down. In this fully general\r\nsetting, the runtime of our algorithms
scales as $2^{cn/2}$ for $c<1$, yielding\r\nthe first quantum algorithms for low-energy
estimation breaking the natural\r\nbound based on Grover search. The core of our
approach is remarkably simple,\r\nand relies on showing that any $k$-body Hamiltonian
has a low-energy subspace\r\nof exponential dimension."

text: "We investigate the role of energy, i.e. average photon number, as a resource\r\nin
the computational complexity of bosonic systems. We show three sets of\r\nresults:
(1. Energy growth rates) There exist bosonic gate sets which increase\r\nenergy
incredibly rapidly, obtaining e.g. infinite energy in finite/constant\r\ntime.
We prove these high energies can make computing properties of bosonic\r\ncomputations,
such as deciding whether a given computation will attain infinite\r\nenergy, extremely
difficult, formally undecidable. (2. Lower bounds on\r\ncomputational power) More
energy ``='' more computational power. For example,\r\ncertain gate sets allow
poly-time bosonic computations to simulate PTOWER, the\r\nset of deterministic
computations whose runtime scales as a tower of\r\nexponentials with polynomial
height. Even just exponential energy and $O(1)$\r\nmodes suffice to simulate NP,
which, importantly, is a setup similar to that of\r\nthe recent bosonic factoring
algorithm of [Brenner, Caha, Coiteux-Roy and\r\nKoenig (2024)]. For simpler gate
sets, we show an energy hierarchy theorem. (3.\r\nUpper bounds on computational
power) Bosonic computations with polynomial\r\nenergy can be simulated in BQP,
``physical'' bosonic computations with\r\narbitrary finite energy are decidable,
and the gate set consisting of Gaussian\r\ngates and the cubic phase gate can
be simulated in PP, with exponential bound\r\non energy, improving upon the previous
PSPACE upper bound. Finally, combining\r\nupper and lower bounds yields no-go
theorems for a continuous-variable\r\nSolovay--Kitaev theorem for gate sets such
as the Gaussian and cubic phase\r\ngates."

text: "The Quantum k-SAT problem is the quantum generalization of the k-SAT problem.\r\nIt
is the problem whether a given local Hamiltonian is frustration-free.\r\nFrustration-free
means that the ground state of the k-local Hamiltonian\r\nminimizes the energy
of every local interaction term simultaneously. This is a\r\ncentral question
in quantum physics and a canonical QMA_1-complete problem. The\r\nQuantum k-SAT
problem is not as well studied as the classical k-SAT problem in\r\nterms of special
tractable cases, approximation algorithms and parameterized\r\ncomplexity. In
this paper, we will give a graph-theoretic study of the Quantum\r\nk-SAT problem
with the structures core and radius. These hypergraph structures\r\nare important
to solve the Quantum k-SAT problem. We can solve a Quantum k-SAT\r\ninstance in
polynomial time if the derived hypergraph has a core of size n-m+a,\r\nwhere a
is a constant, and the radius is at most logarithmic. If it exists, we\r\ncan
find a core of size n-m+a with the best possible radius in polynomial time,\r\nwhereas
finding a general minimum core with minimal radius is NP-hard."
