Quantum Computing Files: Tuesday's edition (June 29)
Quantum Computing Files: a newsletter about Quantum.
Hello welcome back to the Quantum Computing Files: Tuesday edition today June 29th.
Quantum Computing UK is a new project working in Quantum Computing originated in the UK (United Kingdom). One of its founders is a person (engineer/researcher), Macauley Coggins, with whom I had the pleasure to speak personally over a mobile phone conversation some months ago and is a connection on a well known professional social network. This project is publishing the main relevant algorithmic and software developments possible in Quantum Computing these days with the devices we today call Quantum Computers, at their state-of-the art hardware possibilities. There is also already announced the publishing of a book, and in the website we can read now some of the excerpts that will become the books' content. I also get in this bandwagon with Quantum Computing UK today and publish here the first link to a tutorial recently published there (the newcomer reader might need to explore back previous articles for context…). I am convinced it will be the first of many more to come. This first installement here is about controlled Hadamard gates in Qiskit with Code provided.
On techology news in this edition I share a recently received link from Inside HPC reporting about how Rigetti Computing - a Quantum Computing hardware and full-stack developer - has launched a scalable Multi-Chip Quantum Processor. Interesting, specially within an industry - chip manufacturing - experiencing a somewhat desperate need of positive productivity news…
Within the usual set of business news about Quantum Computing I forward again content from The Quantum Daily publication, this time coming back to Quantum Computing in banking/financial systems applications, with a list of banking institutions (eleven in total) already involved with this technology, with different stages of development, but all showing serious committment.

CONTROLLED HADAMARD GATES IN QISKIT WITH CODE (June 28th)
Introduction
In this tutorial we will explore how to implement a controlled Hadamard gate on IBM’s quantum computers with Qiskit.
This tutorial is an excerpt from our upcoming textbook Introduction to Quantum Computing with Qiskit.
A controlled Hadamard gate is a controlled gate consisting of two qubits. When the control qubit is |1〉it will apply a Hadamard gate (and the qubits will become in superposition) to the target qubit.
In Qiskit we can implement a Controlled Hadamard gate very easily by applying a Pauli X gate to the control qubit and then applying the Controlled Hadamard gate. Then we measure both qubits.
Technology Breakthrough in Rigetti
Rigetti Launches Scalable Multi-chip Quantum Processor (Inside HPC - June 29th)
BERKELEY, Calif.— June 29, 2021 — Rigetti Computing, a full-stack quantum computing company, announced today it is launching what it said is the world’s first multi-chip quantum processor. The processor incorporates a proprietary modular architecture that accelerates the path to commercialization and solves key scaling challenges toward fault-tolerant quantum computers. Rigetti expects to make an 80-qubit system powered by the breakthrough multi-chip technology available on its Quantum Cloud Services platform later this year.
“There is a race to get from the tens of qubits that devices have today, to the thousands of qubits that future systems will require to solve real-world problems,” says Amir Safavi-Naeini, assistant professor of applied physics at Stanford. “Rigetti’s modular approach demonstrates a very promising way of approaching these scales.”

11 Global Banks Probing The Wonderful World of Quantum Technologies (The Quantum Daily - June 23rd)
Shifting Strategies
It’s a common fact now (or is it?) that many calculations can be performed much more efficiently on a quantum computer than on any existing classical computer or even supercomputer. There are more than a few experts who believe this is a potential gamechanger, especially in sectors like banking, where quantum algorithms could be applied to problems in Value at Risk (VAR) calculations and portfolio volatility optimization.
TQD will now list eleven major banks with visible quantum programs, either in their early stages or full-blown initiatives. They stretch from the US, Canada, the UK all the way to Japan. Unfortunately, no Chinese banks have been included, but we will leave that topic for another article at a later date.
As usual, the list is exhaustive and does not cover the whole array of activities going on in the summer of 2021. And anyway, if the banking sector is as dynamic as the QC landscape seems to be, we’re certain another dozen banks will have a quantum program in place by the time this post goes live!
Here we just the banking institutions’ names:
JPMorgan Chase
HSBC
BNP Paribas
Crédit Agricole
Japan Post Bank
Citigroup
Wells Fargo
Barclays
Royal Bank of Canada
ING Group
Goldman Sachs
