Floquet codes with a twist
We describe a method for creating twist defects in the honeycomb Floquet code
of Hastings and Haah. In particular, we construct twist defects at the
endpoints of condensation defects, which are built by condensing emergent
fermions along one-dimensional paths. We argue that the twist defects can be
used to store and process quantum information fault tolerantly, and demonstrate
that, by preparing twist defects on a system with a boundary, we obtain a
planar variant of the Floquet code. Importantly, our
construction of twist defects maintains the connectivity of the hexagonal
lattice, requires only 2-body measurements, and preserves the three-round
period of the measurement schedule. We furthermore generalize the twist defects
to Floquet codes defined on -dimensional qudits. As an aside,
we use the Floquet codes and condensation defects to define
Floquet codes whose instantaneous stabilizer groups are characterized by the
topological order of certain Abelian twisted quantum doubles.Comment: 35+7 pages, 19 figures; v2 corrected typos; v3 corrected

Engineering Floquet codes by rewinding
Floquet codes are a novel class of quantum error-correcting codes with
dynamically generated logical qubits, which arise from a periodic schedule of
non-commuting measurements. We engineer new examples of Floquet codes with
measurement schedules that during each period. The rewinding
schedules are advantageous in our constructions for both obtaining a desired
set of instantaneous stabilizer groups and for constructing boundaries. Our
first example is a Floquet code that has instantaneous stabilizer groups that
are equivalent -- via finite-depth circuits -- to the 2D color code and
exhibits a automorphism of the logical operators. Our second
example is a Floquet code with instantaneous stabilizer codes that have the
same topological order as the 3D toric code. This Floquet code exhibits a
splitting of the topological order of the 3D toric code under the associated
sequence of measurements i.e., an instantaneous stabilizer group of a single
copy of 3D toric code in one round transforms into an instantaneous stabilizer
group of two copies of 3D toric codes up to nonlocal stabilizers, in the
following round. We further construct boundaries for this 3D code and argue
that stacking it with two copies of 3D subsystem toric code allows for a
transversal implementation of the logical non-Clifford gate. We also show
that the coupled-layer construction of the X-cube Floquet code can be modified
by a rewinding schedule such that each of the instantaneous stabilizer codes is
finite-depth-equivalent to the X-cube model up to toric codes; the X-cube
Floquet code exhibits a splitting of the X-cube model into a copy of the X-cube
model and toric codes under the measurement sequence. Our final example is a
generalization of the honeycomb code to 3D, which has instantaneous stabilizer
codes with the same topological order as the 3D fermionic toric code.Comment: 20+3 pages, 27 figures, files are available at

Establishing a Conditional Signal for Assistance in Teenagers with Blindness
Five teenagers with severe intellectual impairments and no discernible communication skills were enrolled in training to teach a conditional request for assistance using a speech-generating device (SGD). All were either blind or severely visually impaired since birth. All learned to operate an adaptive switch to control sensory outcomes, next showed preferences among sensory outcomes, and then demonstrated the ability to use their switch to signal for assistance with an SGD when the sensory outcome was remotely disabled. During the signaling phase, or subsequent attempts to generalize its use outside the laboratory, 3 participants began vocalizing. Most notably, they began imitation of the word “song” or the word “help” emitted by the SGD. The potential role of cause-and-effect training with adaptive switches is discussed
Pauli topological subsystem codes from Abelian anyon theories
We construct Pauli topological subsystem codes characterized by arbitrary
two-dimensional Abelian anyon theories--this includes anyon theories with
degenerate braiding relations and those without a gapped boundary to the
vacuum. Our work both extends the classification of two-dimensional Pauli
topological subsystem codes to systems of composite-dimensional qudits and
establishes that the classification is at least as rich as that of Abelian
anyon theories. We exemplify the construction with topological subsystem codes
defined on four-dimensional qudits based on the anyon
theory with degenerate braiding relations and the chiral semion theory--both of
which cannot be captured by topological stabilizer codes. The construction
proceeds by "gauging out" certain anyon types of a topological stabilizer code.
This amounts to defining a gauge group generated by the stabilizer group of the
topological stabilizer code and a set of anyonic string operators for the anyon
types that are gauged out. The resulting topological subsystem code is
characterized by an anyon theory containing a proper subset of the anyons of
the topological stabilizer code. We thereby show that every Abelian anyon
theory is a subtheory of a stack of toric codes and a certain family of twisted
quantum doubles that generalize the double semion anyon theory. We further
prove a number of general statements about the logical operators of translation
invariant topological subsystem codes and define their associated anyon
theories in terms of higher-form symmetries.Comment: 67 + 35 pages, single column forma

An Appraisal of the Current Scenario in Vaccine Research for COVID-19
The recent coronavirus disease 2019 (COVID-19) outbreak has drawn global attention, affecting millions, disrupting economies and healthcare modalities. With its high infection rate, COVID-19 has caused a colossal health crisis worldwide. While information on the comprehensive nature of this infectious agent, SARS-CoV-2, still remains obscure, ongoing genomic studies have been successful in identifying its genomic sequence and the presenting antigen. These may serve as promising, potential therapeutic targets in the effective management of COVID-19. In an attempt to establish herd immunity, massive efforts have been directed and driven toward developing vaccines against the SARS-CoV-2 pathogen. This review, in this direction, is aimed at providing the current scenario and future perspectives in the development of vaccines against SARS-CoV-2
