IBM: Three Demonstrations Prove Quantum Advantage Has Been Reached
6 hours ago
- IBM and partners claim quantum advantage with three demonstrations on Heron chip, meeting criteria of accuracy, cost, and validation.
- Algorithmiq simulated real-world disordered materials; classical systems could not reproduce results after eight months.
- Qedma simulated externally driven materials; quantum system ran in 7 hours vs. classical needing 700,000 CPU hours.
- University of Chicago created structured alternative to random circuit sampling, running 70 logical qubits with error correction in 16 minutes.

NIST Develops New Standards to Safeguard Computers Against Quantum Threats
14 hours ago
- Cryptography protects data using math problems that are hard for current computers but quantum computers could break them.
- Post-quantum cryptography (PQC) aims to create new algorithms resistant to quantum computer attacks.
- The 'harvest now, decrypt later' threat means adversaries can collect encrypted data now and decrypt it later with quantum computers.
- NIST is developing new cryptographic standards through an open, transparent process involving global researchers.

We accidentally built an LLVM compiler for Jax
3 days ago
- The Catalyst quantum compiler for PennyLane accidentally supports pure classical JAX code, compiling it to MLIR and LLVM without quantum instructions.
- The team chose JAX because it can trace Python functions, supports NumPy and SciPy APIs, and lowers to MLIR, while adding native Python control flow and dynamic shapes.
- The goal was to compile entire hybrid quantum-classical workflows into standalone executables, not just quantum instructions.
- Catalyst bypasses XLA, lowering JAX representations directly to standard MLIR dialects and then to LLVM, enabling use of LLVM tools like Enzyme for backpropagation.

How to measure the performance of a quantum computer
2 days ago
- Quantum computer performance is evaluated using three metrics: programmable qubits, qubit operations, and maximum circuits per second.
- Programmable qubits measure scale as the number of qubits users can directly control in algorithms.
- Qubit operations measure quality by indicating how many complex two-qubit operations a system can reliably execute.
- Maximum circuits per second measures speed and circuit throughput, key for price-performance and cost efficiency.

Mythos attack on 3rd-round PQC algorithm candidate puts it out of commission
4 days ago
- The HAWK quantum-resistant cryptography algorithm was withdrawn from NIST consideration after Anthropic's Mythos AI model found a security flaw that made it broken.
- HAWK had passed two rounds of NIST testing for PQC algorithms but failed in the third round designed to catch advanced flaws.
- Mythos AI also identified weaknesses in the AES cipher, though both findings are described as incremental and not breaking current systems.
- The tests used weakened versions of cryptosystems; the real versions used in production are more robust.

DOE Launching First Fault-Tolerant Quantum Computer Initiative
9 days ago
- The U.S. Department of Energy launched the Quantum Genesis initiative to develop the world's first fault-tolerant quantum computer for research by 2028.
- The initiative is part of the broader Genesis Mission and aligns with President Trump's executive order on quantum innovation.
- Three main priorities: the DOE Q Competition to demonstrate quantum systems with logical qubits by 2028, a National Quantum Supercomputing User Facility for multi-modal quantum access, and focused R&D for quantum applications.
- The effort aims to integrate quantum computing with AI and high-performance computing to strengthen U.S. leadership in science and technology.

Spatial languages: Writing code in 2D
11 days ago
- The article proposes using 2D spatial notation for programming expressions, allowing vertical writing of infix operators.
- Introduces `andFlip`, a 3-arity operator that toggles a target when both inputs are true, motivating vertical chaining.
- Shows how vertical chaining can reset mutable variables within the same expression, inspired by quantum computing's ancilla uncomputation.
- Demonstrates a 3-bit adder using spatial operators `maj` and `uma`, which clean up after themselves.

Scientists' Side Hustle? Using AI and Quantum Computing to Generate New Peptides
22 days ago
- Researchers demonstrated that quantum computers can enhance the accuracy and scope of generative AI models for drug discovery.
- A hybrid quantum-classical system accelerated AI to generate novel peptides, improving binding prediction to target proteins, especially with scarce training data.
- The project was self-funded by the team using spare time and leftover money, as innovative science is often deemed risky by traditional funders.
- The approach could speed up personalized immunotherapies, vaccines, and drug efficacy for understudied populations, addressing data gaps in non-Western genetic diversity.
