QUICK BYTE: Scientists from the University of Sydney and Q-CTRL demonstrated a universal quantum gate set for Gottesman-Kitaev-Preskill (GKP) logical qubits using trapped ions.

DETAILS: 

  • University of Sydney and Q-CTRL researchers demonstrated a universal quantum gate set for Gottesman-Kitaev-Preskill (GKP) logical qubits using trapped ions. They achieved single-qubit gate process fidelities of 0.960 and two-qubit entangling gate fidelities of 0.680, with logical qubits encoded in the harmonic motion of ions.

  • They used computer-optimized control techniques to adjust the interaction between the ions' spins and their motion using laser pulses, preserving the structure of the GKP qubits, which have limited energy, and reducing errors during quantum gate operations.

  • A key outcome was the direct creation of a GKP Bell state with a fidelity of 0.842 in a single step from the ground state, showing that highly entangled states can be efficiently generated.

  • This work provides an example of a hardware-efficient approach to encoding qubits in harmonic oscillators, which could be used to reduce the physical qubit overhead typically required for quantum error correction.

QUICK BYTE: Physicists from the Cavendish Laboratory in Cambridge have created the first two-dimensional version of the Bose glass, a new phase of matter, by cooling ultracold atoms in a laser-induced quasiperiodic pattern, relevant for applications in quantum computing.

DETAILS: 

  • Physicists from the Cavendish Laboratory in Cambridge created the first two-dimensional Bose glass, a phase of matter where all particles are localized, preventing them from mixing with their neighbors.

  • Overlapping laser beams were used to form a quasiperiodic pattern and filled with ultracold atoms cooled to nanokelvin temperatures, leading to the formation of the Bose glass. The glass displays non-ergodic behavior, meaning it retains its initial conditions.

  • This research is significant because the Bose glass could advance quantum computing by preserving quantum information for longer, as localized systems do not mix with their environment, reducing the issue of decoherence.

  • Additionally, the experiment revealed a sharp phase transition from Bose glass to superfluid, offering insights into how these distinct phases coexist and confirming theoretical predictions about the Bose-Hubbard model.

QUICK BYTE: Moth, a quantum technology startup, has hired prominent researcher James Wootton as its Chief Science Officer to lead the development of quantum computing applications in gaming, including procedural generation, AI, and graphics.

DETAILS: 

  • Moth, a London-based startup focused on integrating quantum technology into music, gaming, and the arts, has hired prominent researcher James Wootton as its first Chief Science Officer.

  • Wootton, a former IBM quantum researcher, will lead Moth’s scientific efforts to develop quantum algorithms for procedural content generation, character AI, and graphics to rewrite the standard of how games are created and experienced.

  • Moth has raised over $3 million to date and is working on utilizing NISQ computers to create new creative tools for game developers, with plans to extend these innovations to the music and visual media industries.

  • The company is preparing to release its first major product this year, focusing on combining quantum computing and generative AI for content creation.

QUICK BYTE: Atom Computing and Microsoft have partnered to develop the world's most powerful quantum computer, using Atom Computing's neutral atom technology.

DETAILS: 

  • Atom Computing and Microsoft have announced a collaboration to develop the world's most powerful quantum computer, with intentions to achieve fault-tolerant quantum computing using Atom Computing's neutral atom technology.

  • The partnership will focus on creating logical qubits through quantum error-correction, which groups multiple physical qubits to form a single qubit with low error rates, allowing quantum computers to run complex algorithms that are resistant to the imperfections of physical qubits.

  • Atom Computing's second-generation systems, with large numbers of high-fidelity qubits, all-to-all qubit connectivity, long coherence times, and qubit reset capabilities, will be used to demonstrate logical qubits and co-develop fault-tolerant quantum algorithms with Microsoft.

Los Alamos National Laboratory’s Quantum Computing Summer School provided 21 students with hands-on experience in quantum computing, allowing them to work on cutting-edge research alongside expert mentors, including researchers from Xanadu.
