PRESENTATION TITLE

Quantum Computing: Towards the Road to Advantage

ABSTRACT

The theory of quantum mechanics predicts that a group of particles can be entangled, and thus their collective behavior is more complex than a description that treats them individually and independently. When applied to bits in a computer, quantum entanglement predicts that the computational space spanned by N qubits can grow exponentially. Preserving coherence in a quantum processor capable of accessing 2^N distinct configurations, efficiently controlling these states with classical electronics, correcting for errors in real-time using additional qubits, and developing algorithms that effectively employ entanglement for impactful calculations all represent contemporary challenges in realizing a machine that can demonstrate computational advantage over modern classical computers. Superconducting circuits are at the forefront of emerging quantum computing technologies. I will highlight recent milestones in the field, paying particular attention to developments in error correction, and quantum simulations that have shed light on new states of magnetic matter.

PRESENTATION TITLE

Celebrating the 40^th Anniversary of HTS: Past, Present, and Future

ABSTRACT

The 1987 discovery¹ of high-temperature superconductivity (HTS) at 93 K in YBCO, above the liquid-nitrogen temperature and against all theoretical predictions and prevailing beliefs of the time, was hailed as a major advancement in modern physics, as noted in a 1987 US government report. The memorable “Woodstock of Physics”, attended by more than a thousand physicists and featuring dozens of presentations on this and other recent HTS studies², was subsequently held in the evening of March 18 until the next morning during the 1987 APS March Meeting at the New York Hilton. With its potential for further scientific advancement and its technological implications, the discovery of HTS thus generated immense excitement worldwide in the scientific community and beyond, ushering in an unprecedented “gold rush” that has lasted until today. As an old soldier in the trenches, in this presentation I will recall several of the interesting events that heralded the exciting era of HTS, summarize the current status of HTS, and briefly examine its future. I will also show how to advance HTS by enhancing its record ambient T_c³ to 151 K by following the simple route of pressure-quench, bypassing the complexities of chemistry.

PRESENTATION TITLE

From SLUGs to Macroscopic Quantum Phenomena

ABSTRACT

For my research at Cambridge University my thesis advisor, Brian Pippard, suggested a project requiring a voltage sensitivity of 10^-12 to 10^-13 VHz^-1/2. The state of the art was 10^-9 VHz^-1/2. Shortly after my arrival, Brian Josephson presented a seminar on his research. From the knowledge I learned from his talk, I invented the Superconducting Low-Inductance Undulatory Galvanometer, which consisted of a blob of PbSn solder melted around a piece of Nb wire. This enabled me to achieve a sensitivity of 10^-14 VHz^-1/2 and thus write my thesis. Early in 1968 I moved to the University of California, Berkeley. In 1980 John Martinis joined my group as a graduate student and in 1982 Michel Devoret joined as a postdoctoral scholar. We worked on a challenging question proposed by Tony Leggett: Do macroscopic variables obey quantum mechanics? This research resulted in the publication of two Physical Review Letters in 1985: Energy-Level Quantization in the Zero-Voltage State of a Current-Biased Josephson Junction and Measurements of Macroscopic Quantum Tunneling out of the Zero-Voltage State of a Current-Biased Josephson Junction. The combination of these two publications provided overwhelming evidence for the existence of energy quantization and macroscopic quantum tunneling in an electrical circuit.

PRESENTATION TITLE

The Quantum Volt: How the Josephson Effect Revolutionized Standards and Measurement

ABSTRACT

The macroscopic quantum behavior of the Josephson effect has fundamentally transformed global measurement science, particularly within voltage metrology. Following the experimental verification of Josephson’s 1962 discovery, the effect was rapidly applied to voltage standards. However, 57 years elapsed before the International System of Units was officially redefined, allowing the Josephson voltage standard to realize the SI unit of the volt. Exploiting this quantum effect—while simultaneously advancing the materials and techniques required to fabricate superior, more reliable, and user-friendly circuits—has enabled novel measurement paradigms for voltage metrology and radio-frequency (RF) signal applications.

The most significant breakthroughs have occurred in voltage signal synthesis by exploiting the perfectly quantized pulses of Josephson junctions. These Josephson arbitrary waveform synthesizer (JAWS) systems generate AC voltage signals with unprecedented accuracy and precision. Furthermore, novel techniques have progressively extended JAWS capabilities to the higher frequencies required for RF communications. This presentation describes the breakthrough technologies that enabled unique Josephson circuit designs featuring advanced functionality and enhanced signal performance. These innovations in circuits and systems have continually improved DC and AC voltage measurements, electronic-based primary thermometry, and precision signal synthesis for RF communications.

I’ll demonstrate the quantum-locking range feature of Josephson circuits that guarantees the continuous production of quantum-accurate waveforms. I’ll review the specific and novel techniques developed to transfer signal accuracy from the cryogenic circuit to room-temperature devices. I’ll review the multiple reasons why Josephson voltage standard signals have been limited to frequencies below 20 GHz and describe some recent advancements that are finally allowing us to overcome the fundamental challenges of extending these quantum-accurate signals into the terahertz range.

HTS Tapes in Coil Systems: Performance Requirements and Practical Limitations

In the expanding field of high-temperature superconductor (HTS) tape applications, coil technologies impose particularly demanding requirements on tape performance. Key factors include consistent critical current along the entire tape length, uniform geometrical and intrinsic properties, and the availability of long, defect-free lengths. Electro-mechanical performance is especially critical, as HTS tapes must withstand various types of applied stress—such as delamination, hoop, and compressive stress, as well as combinations of these.

Thermal stability and quench protection are also widely discussed within the HTS community. Alongside these challenges, reliable joint technologies for connecting individual tapes or HTS cables remain essential for coil systems, whether in compact high-field magnets, large fusion devices, or accelerator coils. For accelerator applications, mitigating AC losses is a key issue that must be addressed to enable the practical adoption of HTS tapes.

Because HTS tapes must operate within a structural environment, the properties of the surrounding materials must also be carefully evaluated. These considerations, together with comprehensive modelling of the entire assembly, are essential for designing a reliable coil architecture.

In this special session, these topics are addressed to provide a comprehensive understanding of the current status and practical limitations of HTS tapes for coils applications.

Radiation Issues for Superconducting Fusion Magnets

Nuclear fusion based on magnetically confined plasma has attracted renewed interest because of the urgent need for renewable, emission free energy sources. The commercial availability of HTS wires is key for the development of affordable fusion reactors because of their ability to generate large fields leading to a higher power density in the plasma that enables more compact reactor designs. However, a compact design leads to a high radiation load and challenges the materials surrounding the plasma, in particular the superconductors of the toroidal magnet system. This special session aims at giving an overview on the current knowledge about the expected radiation environment, the induced damage and the resulting changes of the properties of the used materials.
