**Quick Recap**

Oxford Quantum Circutis raises $47M in. a series A in the UK. And Quantum Source in Israel $15M leaving stealth mode. A great article by Doug Finke on how to price quantum algorithms and a couple of papers on QML. But besides that, **THE** announcement this week has been about the finalist in the post quantum algorithm race by NIST.

Full article in the NIST website here.

What does this mean? That very soon we will have a replacement for RSA and all our communications. If your company transfers information over any network… it will be impacted and you better get ready soon both for Post Quantum Cryptography, as well as Quantum Communications. And if you don’t know where to start… ask me!

We have the Quantum Definitions by @quantumfyed back!

What are and how to avoid barren plateaus in Quantum Machine Learning? A thread:

## Quantum hacking is the next big cybersecurity threat. Here’s how companies should prepare for ‘Y2Q’

Yahoo! Marriott International. Myspace. Under Armour. EBay. LinkedIn. Just what do these large companies have in common? The answer, as you may have guessed, is that these six corporations have been the victims of the biggest data breaches in the 21st century, with the number of those affected ranging from 117 million executives (LinkedIn in 2012) to as many as 3 billion users (Yahoo in 2013). Such mega virtual break-ins can cost companies hundreds of millions of dollars, but even standard data breaches can be expensive, especially after taking into account the loss of reputation and customers.

## Taking quantum control of life's building blocks

Life (as we know it) is based on carbon. Despite its ubiquity, this important element still holds plenty of secrets, on earth and in the heavens above us. For example, astrophysicists like Columbia's Daniel Wolf Savin who study interstellar clouds want to understand how the chemicals, including carbon, swirling within these nebulous aggregations of gas and dust form the stars and planets that dot our universe and give rise to organic life.

## How Should Quantum Computations Be Priced?

The resources needed are 1) qubits and 2) runtime. The unit of quantum computation should be the qubit-second. However, at the moment, that is not how quantum computation services are priced. With more qubits you can run computations with less steps.

## Paper: Interaction Energies on Noisy Intermediate-Scale Quantum Computers

The computation of interaction energies on noisy intermediate-scale quantum (NISQ) computers appears to be challenging with straightforward application of existing quantum algorithms. For example, use of the standard supermolecular method with the variational quantum eigensolver (VQE) would require extremely precise resolution of the total energies of the fragments to provide for accurate subtraction to the interaction energy. Here we present a symmetry-adapted perturbation theory (SAPT) method that may provide interaction energies with high quantum resource efficiency. Of particular note, we present a quantum extended random-phase approximation (ERPA) treatment of the SAPT second-order induction and dispersion terms, including exchange counterparts. Together with previous work on first-order terms, this provides a recipe for complete SAPT(VQE) interaction energies up to second order. The SAPT interaction energy terms are computed as first-level observables with no subtraction of monomer energies invoked, and the only quantum observations needed are the the VQE one- and two-particle density matrices. We find empirically that SAPT(VQE) can provide accurate interaction energies even with coarsely optimized, low circuit depth wavefunctions from the quantum computer, simulated through ideal statevectors. The errors on the total interaction energy are orders of magnitude lower than the corresponding VQE total energy errors of the monomer wavefunctions.

## Quantum Flytrap – Shaping the Future of Quantum DevTools

Quantum computing is currently at the same level of sophistication as using punched cards for normal computing – it’s a tedious, manual process that still very much depends on your quantum hardware.

## NIST Announces First Four Quantum-Resistant Cryptographic Algorithms

NEWS RELEASE — The U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has chosen the first group of encryption tools that are designed to withstand the assault of a future quantum computer, which could potentially crack the security used to protect privacy in the digital systems we rely on every day — such as online banking and email software. The four selected encryption algorithms will become part of NIST’s post-quantum cryptographic standard, expected to be finalized in about two years.

## A Systematic Literature Review of Quantum Computing for Routing Problems

Quantum Computing is drawing a significant attention from the current scientific community. The potential advantages offered by this revolutionary paradigm has led to an upsurge of scientific production in different fields such as economics, industry, or logistics. The main purpose of this paper is to collect, organize and systematically examine the literature published so far on the application of Quantum Computing to routing problems. To do this, we embrace the well-established procedure named as Systematic Literature Review. Specifically, we provide a unified, self-contained, and end-to-end review of 18 years of research (from 2004 to 2021) in the intersection of Quantum Computing and routing problems through the analysis of 53 different papers. Several interesting conclusions have been drawn from this analysis, which has been formulated to give a comprehensive summary of the current state of the art by providing answers related to the most recurrent type of study (practical or theoretical), preferred solving approaches (dedicated or hybrid), detected open challenges or most used Quantum Computing device, among others.
