nar\n\nLecture held in Jefferson 253 and Zoom.\n\nAbstract\nDiscrepancy th
eory tells us that it is possible to partition vectors into sets that look
surprisingly similar to each other. By "surprisingly similar" we mean mu
ch more similar than the sets produced by a random partition. Randomized C
ontrolled Trials are used to test the effectiveness of interventions\, lik
e medical treatments and educational innovations. Randomization is used t
o ensure that the test and control groups are probably similar. When we k
now nothing about the experimental subjects\, a random partition into test
and control groups is the best choice. When we do have prior information
about the experimental subjects\, we can combine the strengths of randomiz
ation with the guarantees of discrepancy theory. This allows us to obtain
more accurate estimates of the effectiveness of treatments\, or to conduc
t trials with fewer experimental subjects. I will survey some fundamental
results in discrepancy theory\, present a model for the analysis of RCTs\,

intractable applications would it actually enable? The question is nuance

de the possibility of a practical quantum advantage for the wide range of
applications that realize only a modest (e.g.\, quadratic) speedup over cl
assical algorithms. This talk will survey work of Google’s Quantum Algor

g\, compiling\, and benchmarking the most promising applications of quantu

antum systems can exhibit highly complex entanglement. Certifying that an
n-qubit state in the experimental lab is close to a highly-entangled targe
t state typically requires deep entangling circuits or exponentially many
single-qubit measurements. In this work\, we prove that almost all n-qubit
target states\, including those with exponential circuit complexity\, can
be certified from only O(n^2) single-qubit measurements. This result is e
stablished by a new technique relating certification to a random walk's mi
xing time. Our protocol has applications for benchmarking the fidelity of
quantum systems and for learning and verifying neural networks\, tensor ne
tworks\, and various other representations of quantum states using only si
ngle-qubit measurements. We show that such verified representations can be
used to efficiently predict highly non-local properties that would otherw
ise require an exponential number of measurements.\n\nPasscode: 657361\n

rrors is one of the central challenges for useful quantum computing\, requ
iring quantum error correction for large-scale processing. However\, the o
verhead in the realization of error-corrected “logical” qubits\, where
information is encoded across many physical qubits for redundancy\, poses
significant challenges to large-scale logical quantum computing. In this
talk we will discuss recent advances in quantum information processing usi
ng dynamically reconfigurable arrays of neutral atoms. With this platform
we have realized programmable quantum processing with encoded logical qubi
ts\, combining the use of 280 physical qubits\, high two-qubit gate fideli
ties\, arbitrary connectivity\, and mid-circuit readout. Using this logica
l processor with various types of error-correcting codes\, we demonstrate
that we can improve logical two-qubit gates by increasing code size\, outp
erform physical qubit fidelities\, create logical GHZ states\, and perform
computationally complex scrambling circuits using 48 logical qubits and h
undreds of logical gates. We find that this logical encoding substantially
improves algorithmic performance with error detection\, outperforming phy
sical qubits at both benchmarking and quantum simulations. These results h
erald the advent of early error-corrected quantum computation\, enabling n
ew applications and inspiring a shift in both the challenges and opportuni
ties that lay ahead.\n\nPasscode: 657361\n

near neural nets can express general continuous multivariate functions. I
will begin by giving a proof. The theorem has often been regarded as "irr
elevant" to machine learning because of the unrealistic precision required
in its representation of Real numbers. I agree with this criticism but wi

proof.\n\nPasscode: 657361\n

\nAbstract\nThe classification of topological phases of quantum matter has
recently been extended to allow constant-depth adaptive local quantum cir
cuits. In this setting\, a fundamental problem is the classification of to
pological phases that become equivalent to the trivial phase under adaptiv
e quantum circuits. These are precisely the topological phases with ground
states that can be prepared by constant-depth adaptive quantum circuits.
In this work we establish such a classification in terms of solvable anyon
theories\, and argue that it is complete.\nSolvable anyon theories are a
vast generalization of solvable groups that includes cyclic nonabelian any
ons\, and anyons with irrational quantum dimensions such as Ising anyons.\
nWe introduce a sequential gauging procedure that can produce a string-net
ground state in any topological phase described by solvable anyons via a
constant-depth adaptive local quantum circuit. We furthermore introduce a
sequential ungauging and regauging procedure to implement string operators
of arbitrary length for any solvable anyon theory via constant-depth adap
tive local quantum circuits. Our general results are demonstrated for the
quantum double of S3 and for several examples that go beyond solvable grou
ps including the doubled Ising theory\, and the Drinfeld center of the Z3
Tambara-Yamagami category.\n\nPasscode: 657361\n

pYUlJVzZqT3lwV2pCT1ZUQT09.\n\nAbstract\nOne potential route toward fault-t
olerant universal quantum computation is to use the non-Abelian topologica
l codes. In this work\, we investigate how to perform computation with a s
pecific non-Abelian topological order---the quantum double model D(S3). By
embedding each on-site Hilbert space into a qubit-qutrit pair\, we explic
itly construct the circuits for creating\, moving\, and measuring all non-
trivial anyons. These circuits incorporate a single non-Clifford gate. We
also design a specific anyon interferometer to measure the total charge of
well-separated anyons remotely\, without fusing them together. These prot
ocols enable the implementation of a universal gate set proposed by Cui et
.al.\, with the possibility to correct the circuit-level noise actively du
ring the computation process. Then\, we show how to encode each physical d
egree of freedom of D(S3) into a novel quantum error correcting code. The
encoding allows reliable realization of all gates in the anyon manipulatio
n circuits\, thereby further reducing the error rate. This suppresses the
anyon error density\, which facilitates the active error correction by D(S
3). Our proposal offers a promising path to realize universal quantum comp
utation in a fault-tolerant manner.\n\nPasscode: 657361\n

here have been several recent breakthroughs constructing good quantum code
s which have N qubits with distance and dimension Ω(N). However\, these c
odes cannot be implemented in 3 dimensions - there is no way to place the
qubits on a lattice so that every check only involves the qubits in some s
mall ball. Bravyi and Terhal have shown that such 3d codes with qubits ca
n have distance at most O(N^2/3) and dimension at most O(N^1/3)\, given th
at distance. In this talk I'll discuss how to construct 3d codes with para
meters that match these bounds. This relies on the known good codes\, a co
nnection between codes and systolic geometry made by Freedman-Hastings\, a

9283357?pwd=MitXVm1pYUlJVzZqT3lwV2pCT1ZUQT09.\n\nAbstract\nQuantum error c
orrection (QEC) is believed to be essential for scalable quantum computati
on\, but its implementation is challenging due to its considerable space-t
ime overhead. Here we report theoretical and experimental advances in redu
cing this overhead. Using dynamically reconfigurable arrays of neutral ato
ms and various types of error-correcting codes\, we demonstrate efficient
manipulation and entanglement of logical qubits using transversal gates\,
including improving entangling gates with code distance and simulating cla
ssically complex scrambling circuits. In implementing these circuits\, we
observe their performance can be substantially improved by accounting for
error propagation during transversal entangling gates and decoding the log
ical qubits jointly. By leveraging this deterministic propagation of error
s\, we show this correlated decoding enables the number of noisy syndrome
extraction rounds between gates to be reduced from O(d) to O(1) in transve
rsal Clifford circuits\, where d is the code distance. We then generalize
this finding to apply to universal computation by developing strategies fo
r handling feed-forward operations and magic state inputs. These technique
s result in new theories of fault-tolerance and in practical reductions to
the cost of large-scale quantum computation by over an order of magnitude
