We have developed a fully functional 20-qubit superconducting quantum computer that is accessible via the cloud and designed for hardware-level experimentation. The system provides users with full pulse-level control and deep access to the underlying hardware, enabling the testing of novel control electronics, components, and system integrations, as well as the demonstration of proof-of-concept quantum hardware implementations beyond standard black-box operation. 

Our experiments are performed on a superconducting quantum processor research platform featuring 120 RF control lines and 8 readout lines, enabling flexible control and readout of medium-scale quantum processors. The platform supports investigations beyond standard transmon systems and is currently used to develop and characterize non-traditional qubit architectures, with a focus on scalable control, novel coupling schemes, and improved hardware performance. 

We operate a hybrid quantum platform that integrates a magneto-optical trap with a dilution refrigerator, enabling the transport of ultracold atoms into the cryogenic environment via a magnetic conveyor belt. Inside the dilution refrigerator, the atoms are brought into controlled interaction with superconducting qubits. This hybrid approach combines the long coherence and intrinsic uniformity of atomic systems with the fast control and maturity of superconducting quantum processors, enabling quantum state transfer between distinct physical platforms and opening new routes toward scalable hybrid quantum architectures. 

We have developed an extremely accurate and robust atomic gravimeter designed for operation outside laboratory environments. The system has been successfully deployed in multiple field gravity surveys in Singapore and surrounding islands, demonstrating stable performance under non-ideal environmental conditions. It supports remote operation, allowing continuous measurements with minimal on-site intervention, and combines high sensitivity with mechanical and operational robustness, making it well suited for real-world geophysical surveys and applied quantum sensing applications. 

We are currently developing a three-axis quantum accelerometer designed to augment navigation systems in GPS-denied environments. The system targets high stability and low drift operation, making it particularly relevant for maritime platforms, where long-duration navigation without external references is critical. It is engineered for robustness and reliable performance under harsh environmental conditions, enabling deployment beyond controlled laboratory settings. 

We have demonstrated wideband electric field sensing using Rydberg atoms, extending detection capabilities from sub-Hz to 10 kHz frequencies. By using paraffin-coated vapor cells to overcome electric-field screening effects, the system achieves sensitivities one to two orders of magnitude better than classical dipole antennas of comparable size in the extremely-low frequency regime. The electrode-free sensor covers sub-ELF, ELF, SLF, ULF, and VLF bands with state-of-the-art sensitivities, enabling applications in underwater communication, geophysical surveys, and low-frequency radio astronomy.
