# Quantum 101 Institute for Quantum Computing

Both superposition and entanglement are, however, difficult to sustain due to the fragility of quantum states, which can be disrupted by minute movements, changes in temperature, or other environmental factors. Quantum technology translates the principles of quantum physics into technological applications. In general, quantum technology has not yet reached maturity; however, it could hold significant implications for the future of military sensing, encryption, and communications, as well as for congressional oversight, authorizations, and appropriations. Our mission statement is to bring useful quantum computing to the world. At this year’s Summit, we demonstrated that we’re well on our way to making that statement a reality, and showed you where we’re going from here. We’re going to continue to provide the best full-stack quantum offering in the industry — and it’s up to the industry to put those full-stack quantum systems to use.

Next year, we’ll release the 133-qubit IBM Quantum Heron processor, based on our new tunable coupler architecture. Heron will be able to combine modularly and incorporate classical communication to speed up workflows, in order to take advantage of Circuit Knitting and Quantum Serverless features. But we can’t just think modularly — we also must scale in a cost-efficient way. So we’re developing our 4K cryo-CMOS qubit controller — which we can use to control qubits from inside the fridge, with a chip the size of a fingernail.

It was discovered that certain computational problems could be tackled more efficiently with quantum algorithms than with their classical counterparts. Entanglement is a quantum mechanical effect that correlates the behavior of two separate things. When two qubits are entangled, changes to one qubit directly impact the other.

## Corporates and big tech companies are going after quantum computing

But all quantum computer makers are headed toward a rosier “fault-tolerant” era in which qubits are better stabilized and ganged together into long-lived “logical” qubits that fix errors to persist longer. That’s when the true quantum computing benefits arrive, likely five or more years from now. But you’d have been hard pressed to find a whiff of pessimism at Q2B, a December conference about the business of quantum computing. Industry players showed continued progress toward practical quantum computers, Ph.D.-equipped researchers from big business discussed their work, and one study showed declining worries about a research and investment freeze.

Over and over at Q2B, quantum computing advocates showed themselves to be measured in their predictions and guarded about promising imminent breakthroughs. Comments that quantum computing will be “bigger than fire” are the exception, not the rule. Quantum computing executives and researchers are acutely aware of the risks of a quantum winter. They saw what happened with artificial intelligence, a field that spent decades on the sidelines before today’s explosion of activity. In Q2B interviews, several said they’re working to avoid AI’s early problems being overhyped. He is a co-author, the “R,” of the PBR theorem, which, along with its better-known predecessor, Bell’s theorem, lays bare the peculiarities of quantum behavior.

The race to build a quantum computer is balanced against patience and technology road maps that stretch years into the future. Three decades after they were first proposed, quantum computers remain

largely theoretical. Even so, there’s been some encouraging progress

toward realizing a quantum machine.

This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers. The Institute for Quantum Optics and Quantum Information (IQOQI) lies within the Austrian Academy of Sciences. Their quantum computing degree programs range from quantum optics to superconducting quantum circuits to quantum nanophysics. With a large staff of researchers and scientists, this quantum computing university sits right in the middle of the quantum hub in Europe. Perhaps the largest center for quantum research in the UK, Oxford University‘s quantum computing graduate program hosts 38 different research teams and over 200 researchers. As their focus is to harness the power of quantum computing, students get hands-on experience developing next-level quantum technology, while being in the center of the UK’s quantum network.

### IBM Think 2023: AI and Quantum Computing

To program an annealing quantum computer, a user maps a problem into a search for the “lowest point in a vast landscape,” corresponding to the best possible outcome. The quantum processing unit considers all the possibilities simultaneously to determine the lowest energy required to form those relationships. The solutions are values that correspond to the optimal configurations of qubits found, or the lowest points in the energy landscape. Another area of finance quantum computers could change are Monte Carlo simulations — a probability simulation used to understand the impact of risk and uncertainty in financial forecasting models.

Millionways’ advanced emotionally-intelligent AI platform uniquely combines analysis and matchmaking algorithms based upon various forms of user-generated text or audio-to-text data with at least 500 words. Unlike other machine learning platforms such as ChatGPT, Alexa, or Siri, the millionways proprietary methodology and algorithms make behavorial predictions based on psychological patterns driven by underlying emotions. The methodology, known as Personality Systems Interactive (PSI) theory, is a recognized and validated model for studying the dynamics of personality development and emotional state. Similar to its experience in AI, IBM was an early adopter and promoter of quantum computing and is actively working to bring quantum solutions to market. It also clearly recognizes the potential dangers that government agencies and enterprises face during the quantum computing transition.

## The Journey to Building a True Quantum

Qudits are similar to the integer types in classical computing, and may be mapped to (or realized by) arrays of qubits. Qudits where the d-level system is not an exponent of 2 can not be mapped to arrays of qubits. “Right now we have quantum computers with very simple microchips,” he said. “What we have achieved here is the ability to realise extremely powerful quantum computers capable of solving some of the most important problems for industries and society.” Computer scientists have been trying to make an effective quantum computer for more than 20 years.

## Quantum-centric supercomputing: The next wave of computing

Quantum computers may one day rapidly find solutions to problems no regular computer might ever hope to solve, but there are vanishingly few quantum programmers when compared with the number of conventional programmers in the world. Now a new beginner’s guide aims to walk would-be quantum programmers through the implementation of quantum algorithms over the cloud on IBM’s publicly available quantum computers. Multilevel systems can be used as well, if they possess two states that can be effectively decoupled from the rest (e.g., ground state and first excited state of a nonlinear oscillator). Several physical implementations that approximate two-level systems to various degrees were successfully realized. Unfortunately, there is no single simple physical

principle from which these conclusions follow – and we must guard against

attempting to describe quantum concepts in classical terms! The best we can do is to distill quantum mechanics down to a few

abstract-sounding mathematical laws, from which all the observed behavior

of quantum particles (and qubits in a quantum computer) can be deduced and

predicted.

### Why is there so much hype about the quantum computer?

Who knows how conventional computers might advance

in the next 50 years, potentially making the idea of quantum computers irrelevant—and even absurd. Quantum computers and classical computers process information differently. A quantum computer uses qubits to run multidimensional quantum algorithms. Superposition and entanglement are two features of quantum physics on which quantum computing is based. They empower quantum computers to handle operations at speeds exponentially higher than conventional computers and with much less energy consumption.
