In particular, memristors are highly anticipated hardware candidates owing to their fast-programming speed, low power consumption, and compatibility with the complementary metal–oxide semiconductor (CMOS) technology. In this review, we start from the basic principles of SNNs, and then introduced memristor-based technologies for hardware implementation of SNNs, and further discuss the feasibility of integrating customized algorithm optimization to promote efficient and energy-saving SNN hardware systems.

However, the power consumption levels of classical electronics may compromise the local chip temperature and hence affect the fidelity of qubit operations. In the current work, a quantum-dot-based thermometer embedded in an industry-standard silicon field-effect transistor (FET) was adopted to assess the local temperature increase produced by an active FET placed in close proximity. The impact of both static and dynamic operation regimes was thoroughly investigated. When the FET was operated statically, a power budget of 45 nW at 100-nm separation was found, whereas at 216 μm, the power budget was raised to 150 μW. Negligible temperature increase for the switch frequencies tested up to 10 MHz was observed when operating dynamically. The current work introduced a method to accurately map out the available power budget at a distance from a solid-state quantum processor, and indicated the possible conditions under which cryoelectronics circuits may allow the operation of hybrid quantum–classical systems.</p></div>","PeriodicalId":100244,"journal":{"name":"Chip","volume":"3 3","pages":"Article 100097"},"PeriodicalIF":0.0,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2709472324000157/pdfft?md5=08ee00550d4fd08f99bd72e49daa1de1&pid=1-s2.0-S2709472324000157-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141508190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is, therefore, beneficial to contrast the measurements of hundreds of devices fabricated in a single chip in one cooldown process to promote the scalability, integrability, reliability, and reproducibility of quantum devices and to save evaluation time, cost and energy. Here, we used a cryogenic on-chip multiplexer architecture and investigated the statistics of the 0.7 anomaly observed on the first three plateaus of the quantized conductance of semiconductor quantum point contact (QPC) transistors. Our single chips contain 256 split gate field-effect QPC transistors (QFET) each, with two 16-branch multiplexed source-drain and gate pads, allowing individual transistors to be selected, addressed and controlled through an electrostatic gate voltage process. A total of 1280 quantum transistors with nano-scale dimensions are patterned in 5 different chips of GaAs heterostructures. From the measurements of 571 functioning QFETs taken at temperatures <em>T</em> = 1.4 K and <em>T</em> = 40 mK, it is found that the spontaneous polarisation model and Kondo effect do not fit our results. Furthermore, some of the features in our data largely agreed with van Hove model with short-range interactions. Our approach provides further insight into the quantum mechanical properties and microscopic origin of the 0.7 anomaly in QFETs, paving the way for the development of semiconducting quantum circuits and integrated cryogenic electronics, for scalable quantum logic control, readout, synthesis, and processing applications.</p></div>","PeriodicalId":100244,"journal":{"name":"Chip","volume":"3 3","pages":"Article 100095"},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2709472324000133/pdfft?md5=5f30d302d84e157cb03adf3d6b99680b&pid=1-s2.0-S2709472324000133-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140757484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have been conducted to optimize the geometries of the radio-frequency (RF) electrodes to generate ideal trapping electric fields with a lower junction barrier and an even ion height of the RF saddle points. However, this iteration is time-consuming and commonly accompanied by complicated and sharp electrode geometry. Therefore, high-accuracy fabrication process and high electric breakdown voltage are essential.

The simulation results show that this method shows the same effect on engineering the trapping potential and reducing the potential barrier, but requires fewer parameters and optimization time. By combining this method with the geometrical shape-optimizing, the pseudo-potential barrier and the ion height variation near the junction can be further reduced. In addition, the geometry of the electrodes can be simplified to relax the fabrication precision and keep the ability to engineer the trapping electric field in real-time even after the fabrication of the electrodes, which provides a potential all-electric degree of freedom for the design and control of the two-dimensional ion crystals and investigation of their phase transition.</p></div>","PeriodicalId":100244,"journal":{"name":"Chip","volume":"3 1","pages":"Article 100078"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2709472323000412/pdfft?md5=24fb94275ac1328ef859f1df70f873a1&pid=1-s2.0-S2709472323000412-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138717373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
