How to protect critical infrastructure in the quantum-computing era

Unique issues are involved in cybersecurity for critical infrastructure (CI) such as petroleum pipelines, power stations, electric utilities, water treatment plants, dams, ports, and mass transport systems. Quantum News Briefs summarizes and August 21 article in Federal times by Darren Pulsipher this describes the need and the ways to protect critical infrastructure in quantum-computing era.
Exploits that target IT might result in exposed data or business disruption. Attacks on operational technology (OT) could result in injury, illness, or worse across cities or regions.
But operational technology (OT)-specific approaches are no longer adequate for safeguarding Critical infrastruction (CI), for two reasons. First, both are becoming interconnected as OT becomes digitized. Second, quantum computing could soon render existing password and data encryption strategies obsolete.
OT managers adhere to the Purdue Model, a framework for industrial control system security, developed at Purdue University in the 1990s. The Purdue Model emphasizes segmentation of operations, processes, controls, and sensors to protect OT from cyberattacks. OT is completely isolated from IT, with the equivalent of a demilitarized zone between them.
The Purdue Model remains a bedrock of OT security. But it’s no longer sufficient, because OT properties are no longer truly separated from IT. OT systems rely on expanding networks of IoT devices. They’re increasingly monitored over remote connections. Some are disconnected from the internet but connected to corporate IT. Others are cut off from IT but exposed to the internet.
Strengthening OT security for the quantum era starts with risk assessment. Many organizations lack a clear picture of how their OT systems are vulnerable – and the potential consequences of those vulnerabilities.Critical infrastructure organizations can leverage assessment tools designed for IT security by using these tools to identify all the resources on the network, down to the firmware level, and uncover security gaps. Keep in mind that if an assessment tool can find a resource on the network, so can an attacker.
An effective tool should provide the organization with a risk score. But remember that the tool is likely designed for IT, not operational technology (OT). The organization needs to understand how the tool calculated the risk score and then factor in OT requirements to gain a true understanding of the vulnerabilities. Now the CI organization can prioritize remediations based on the likelihood of attack, the sensitivity of the data, and the criticality of the infrastructure.

Physicists use vibrations to prevent information loss in quantum computing

The tiniest vibrations creeping in from the outside world can cause a quantum system to lose information. Quantum News Briefs summarizes August 21 SciTech article discussing the use of vibrations to stop information loss.
For instance, even light can cause information leaks if it has enough energy to jiggle the atoms within a quantum processor chip.
“Everyone is really excited about building quantum computers to answer really hard and important questions,” said Joe Kitzman, a doctoral student at Michigan State University. “But vibrational excitations can really mess up a quantum processor.”
However, with new research published in the journal Nature Communications, Kitzman and his colleagues are showing that these vibrations need not be a hindrance. In fact, they could benefit quantum technology.
“If we can understand how the vibrations couple with our system, we can use that as a resource and a tool for creating and stabilizing some types of quantum states,” Kitzman said. What that means is that researchers can use these results to help mitigate information lost by quantum bits, or qubits (pronounced “q bits”).
Johannes Pollanen, the Jerry Cowen Endowed Chair of Physics in the MSU Department of Physics and Astronomy. “It’s almost like junk you don’t want to deal with, but you can learn all kinds of cool stuff about the quantum world when you do.”
Pollanen also leads the Laboratory for Hybrid Quantum Systems, of which Kitzman is a member, in the College of Natural Science. For the experiments led by Pollanen and Kitzman, the team built a system consisting of a superconducting qubit and what are known as surface acoustic wave resonators.
The team’s resonators allowed the researchers to tune the vibrations experienced by qubits and understand how the mechanical interaction between the two influenced the fidelity of quantum information.
“We’re creating a paradigm system to understand how this information is scrambled,” said Pollanen. “We have control over the environment, in this case, the mechanical vibrations in the resonator, as well as the qubit.”
“If you can understand how these environmental losses affect the system, you can use that to your advantage,” Kitzman said. “The first step in solving a problem is understanding it.”
MSU is one of only a few places equipped and staffed to perform experiments on these coupled qubit-mechanical resonator devices, Pollanen said, and the researchers are excited to use their system for further exploration.  Click here to read the SciTechDaily article in-entirety.

Bidnovo omejevanje Kitajske bi lahko otrpilo ​​prednost Singapurja v kvantni tehnologiji

Nastajajoči sektor kvantne tehnologije v Singapurju bi lahko utrpel škodo zaradi številnih omejitev, ki jih uvaja Bidnova administracija, da bi Kitajski odrekla prednost na ključnih tehnoloških področjih, pravi Marvie Basilan piše za International Business Times 14. avgusta.
Nekateri so zaskrbljeni, da bi lahko nedavna prepoved Bidnove administracije nekaterih ameriških naložb na Kitajskem, posebej usmerjena v polprevodnike in mikroelektroniko, umetno inteligenco in kvantno informacijsko tehnologijo, ogrozila Singapur na poti do slave. Singapur je ostal zahodni zaveznik kljub polarizaciji sveta po lanski ruski invaziji na Ukrajino.
Dimitris Angelakis, ustanovitelj Angelsko kvantno računalništvo, glavni raziskovalec Centra za kvantne tehnologije Nacionalne univerze v Singapurju in izredni profesor na Tehnični univerzi na Kreti, je povedal International Business Times da se lahko nekatera kvantna zagonska podjetja v Singapurju, ki so v preteklosti prejela »nekaj kitajske podpore«, zapletejo v spor med Kitajsko in Združenimi državami, tista, ki pridobivajo kvantno strojno opremo za eksperimentalne namene, pa se lahko soočijo z izzivi.
Dejal je, da omejitve Washingtona ne bodo imele večjega učinka na singapursko prizorišče kvantne tehnologije, dokler bosta osnovno znanstveno sodelovanje in komunikacija "svobodna in nenadzorovana".
Omejitve "poudarjajo potrebo Singapurja po krepitvi našega lokalnega ekosistema, spodbujanju znanja in izkušenj ter internem razvoju kvantnih tehnologij," Tommaso Demarie, soustanovitelj in izvršni direktor podjetja za kvantno optimizacijo s sedežem v Singapurju Entropica Labs Rekel IBT.
Singapur ima priložnost, da služi kot kvantno središče ne le za jugovzhodno Azijo, ampak tudi za širši azijski tehnološki prostor, vključno z Japonsko, Indijo in Južno Korejo, če bo lahko spretno krmaril v geopolitični areni. Lahko postane strateški partner za države, "ki se bodo ujele v to tehnološko tekmo med velesilami," je dejal Demarie. Kliknite tukaj, če želite prebrati članek v celoti.
