All realistic quantum systems interact with their environments and thereby must be considered as open quantum systems. When a quantum system is strongly coupled to its environment, the so-called ...

The Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab) has open sourced a new electronics control and measurement system for superconducting quantum processors, ...

Quantum computers can solve certain computational problems much faster than ordinary computers by using specific quantum properties. The basic building blocks of such machines are called quantum-bits ...

When designing a next-generation quantum computer, a surprisingly large problem is bridging the communication gap between the classical and quantum worlds. Such computers need a specialized control ...

This illustration draws a parallel between quantum state tomography and natural language modeling. In quantum tomography, structured measurements yield probability outcomes that are aggregated to ...

Origin Wukong’s developers, Origin Quantum Computing Technology Co., launched China’s fourth-generation self-developed quantum control system supporting over 500 qubits. Named Origin Tianji 4.0, this ...

There are many challenges to build a useful quantum computer. The core issue is that the quantum bits—qubits—that run the quantum calculations are incredibly unreliable, breaking down when they ...

Interdisciplinary teams across the Quantum Systems Accelerator (QSA) are using innovative approaches to push the boundaries of superconducting qubit technology, bridging the gap between today's NISQ ...
