Post quantum encryption?
Is there easy access to tools (Linux and Mac) to encrypt files and/or entire file systems using encryption that is quantum proof? I currently use GPG and LUKS, and just interested in future proofing ...

Gold-Price-forecasting In a personal endevaour to learn about time series analysis and forecasting, I decided to reserach and explore various quantitative forecasting methods.This notebook documents contains the methods that can be applied to forecast gold pri…
An Iterative Model Reduction Scheme for Quadratic-Bilinear Descriptor Systems wi…
We discuss model reduction for a particular class of quadratic-bilinear (QB) descriptor systems. The main goal of this article is to extend the recently studied interpolation-based optimal model reduction framework for QBODEs [Benner et al. '16] to a...
General complex envelope solutions of coupled-mode optics with quadratic or cubi…
The analytic general solutions for the complex field envelopes are derived using Weierstrass elliptic functions for two and three mode systems of differential equations coupled via quadratic $χ_2$ type nonlinearity as well as two mode systems couple...

Unconditionally verifiable blind computation
Blind Quantum Computing (BQC) allows a client to have a server carry out a quantum computation for them such that the client's input, output and computation remain private. A desirable property for any BQC protocol is verification, whereby the client...
The Landscape of the Quantum Start-up Ecosystem
The second quantum revolution has been producing groundbreaking scientific and technological outputs since the early 2000s; however, the scientific literature on the impact of this revolution on the industry, specifically on start-ups, is limited. In...
Noise and Neuronal Heterogeneity
We consider signal transaction in a simple neuronal model featuring intrinsic noise. The presence of noise limits the precision of neural responses and impacts the quality of neural signal transduction. We assess the signal transduction quality in re...
A new description of transverse momentum spectra of identified particles produce…
The transverse momentum spectra of identified particles produced in high energy proton-proton ($p+p$) collisions are empirically described by a new method with the framework of participant quark model or the multisource model at the quark level, in w...
Cholesky decomposition of two-electron integrals in quantum-chemical calculation…
A rigorous analysis is carried out concerning the use of Cholesky decomposition (CD) of two-electron integrals in the case of quantum-chemical calculations with finite or perturbative magnetic fields and gauge-including atomic orbitals. We investigat...
Today's loss by the Houston Texans guarantees that for the 60th straight year, n…
In the Super Bowl era, only one player who was listed on a tOSU roster as quarterback has started a Super Bowl: Joe Burrow, who transferred and was eventually drafted out of LSU....
Low overhead quantum computation using lattice surgery
When calculating the overhead of a quantum algorithm made fault-tolerant using the surface code, many previous works have used defects and braids for logical qubit storage and state distillation. In this work, we show that lattice surgery reduces the...
Probing spin relaxation in an individual InGaAs quantum dot using a single elect…
We demonstrate all optical electron spin initialization, storage and readout in a single self-assembled InGaAs quantum dot. Using a single dot charge storage device we monitor the relaxation of a single electron over long timescales exceeding 40μs....
Direct observation of metastable hot trions in an individual quantum dot
Magneto photoluminescence and excitation spectroscopy are used to probe the excited state spectrum of negatively charged trions in a InGaAs quantum dot. A single dot optical charging device allows us to selectively prepare specific few (1e, 2e) elect...
Continuous-time dynamics and error scaling of noisy highly-entangling quantum ci…
We investigate the continuous-time dynamics of highly-entangling intermediate-scale quantum circuits in the presence of dissipation and decoherence. By compressing the Hilbert space to a time-dependent "corner" subspace that supports faithful represe...
High-Q Nanophotonic Resonators on Diamond Membranes using Templated Atomic Layer…
Integrating solid-state quantum emitters with nanophotonic resonators is essential for efficient spin-photon interfacing and optical networking applications. While diamond color centers have proven to be excellent candidates for emerging quantum tech...
Mixing Times in Quantum Walks on the Hypercube
The mixing time of a discrete-time quantum walk on the hypercube is considered. The mean probability distribution of a Markov chain on a hypercube is known to mix to a uniform distribution in time O(n log n). We show that the mean probability distr...
Criteria for universality of quantum gates
We consider the problem of deciding if a set of quantum one-qudit gates $\mathcal{S}=\{U_1,\ldots,U_n\}$ is universal. We provide the compact form criteria leading to a simple algorithm that allows deciding universality of any given set of gates in a...
Evidence for Absorption due to Highly-Ionized Gas in the Radio-quiet Quasar PG 1…
We present results on the X-ray spectrum of the quasar PG 1114+445 from an ASCA observation performed in 1996 June, and a ROSAT observation performed 3 years earlier. We show good agreement between all the datasets can be obtained if the underlying...
Quantum antiferromagnet bluebellite comprising a maple-leaf lattice made of spin…
Spin-1/2 maple leaf lattice antiferromagnets are expected to show interesting phenomena originating from frustration effects and quantum fluctuations. We report the hydrothermal synthesis of a powder sample of bluebellite Cu$_6$IO$_3$(OH)$_{10}$Cl as...
