Measuring Arbitrary Physical Properties in Analog Quantum Simulation (Choi Group)

Quantum simulators—carefully engineered and programmable quantum systems—provide an exciting avenue to explore the laws of nature and to realize complex physical phenomena. However, current quantum simulators still lack the sophisticated controls needed to interrogate a prepared state in depth, limiting the information that can be extracted by measurements. Here, we propose a novel measurement protocol...

Quantum Scrambling with Time-Reversal: A Powerful Tool for Exponentially Enhanced Metrology

The quantum analog of chaotic dynamics, quantum scrambling, spread quantum information exponentially fast within a quantum many-body system. Understanding how the information spread is a highly nontrivial and crucial question in the field of quantum information science (QIS). Recently, it has been theoretically argued that quantum scrambling is intimately connected with quantum metrology (QM), where...

Field programmable spin arrays for scalable quantum repeaters

 In the progress report, it was noted that for “quantum computational advantage” in harnessing many-body quantum stages with spins, large scale control over thousands of spin qubits and their interaction was needed, but was limited by power consumption and cross-talk inherent in current microwave techniques. To this end, we analyzed the problem from first principles...

Engineers discover a new way to control atomic nuclei as “qubits”

In principle, quantum-based devices such as computers and sensors could vastly outperform conventional digital technologies for carrying out many complex tasks. But developing such devices in practice has been a challenging problem despite great investments by tech companies as well as academic and government labs. Today’s biggest quantum computers still only have a few hundred...

Physicists observe rare resonance in molecules for the first time

If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the material’s own natural frequency can send its vibrations into overdrive, causing the glass to shatter. Resonance also occurs at...
