Data underlying the PhD thesis: Quantum Acoustics with high-overtone bulk resonators and superconducting qubits

We measured a transmon qubit coupled to an High-overtone Bulk Acoustic Resonator (HBAR) which was fabricated in the cleanroom of Kavli Nanolab Delft.<br>The fabricated chip was cooled down to ~20 mK in a commercially bought cryofree dilution refrigerator (Oxford Instruments Triton 200). All measurements (single and two tone spectroscopy) were performed on a Vector Network Analyzer (VNA, Keysight PNA N5222A, 10MHz-26.5 GHz) which was connected to the sample using microwave RF cables. Using additional signal generators (Rohde &amp; Schwarz, SMB 100A, 100 kHz - 12.75 GHz) we were able to produce more needed continuous wave tone to AC-Stark shift the qubit. A pulse generator (Rigol DG1022) in combination with a microwave switch (Taylor MW switch SBS-A01TS), both connected to the VNA were used to performed gated two tone spectroscopy for time domain measurement.

我们对与高泛音体声波谐振器（High-overtone Bulk Acoustic Resonator, HBAR）耦合的传输门量子比特（transmon qubit）开展了测量，该器件在代尔夫特卡夫利纳米实验室（Kavli Nanolab Delft）的洁净室中制备。<br>所制备的芯片在商用无液氦稀释制冷机（牛津仪器Triton 200，Oxford Instruments Triton 200）中被冷却至约20毫开尔文。所有测量（单频与双频光谱测量）均在矢量网络分析仪（Vector Network Analyzer, VNA，是德科技PNA N5222A型，工作频段10MHz-26.5 GHz）上完成，该仪器通过微波射频线缆连接至测试样品。通过额外配置的信号发生器（罗德与施瓦茨SMB 100A型，Rohde & Schwarz SMB 100A，工作频段100 kHz - 12.75 GHz），我们可生成所需的额外连续波信号以实现量子比特的AC斯塔克频移。配合连接至矢量网络分析仪的脉冲发生器（普源DG1022型，Rigol DG1022）与微波开关（泰勒微波开关SBS-A01TS，Taylor MW switch SBS-A01TS），我们可开展门控双频光谱测量以完成时域表征。
