When we have enough auxiliary qubits, we have an efficient decomposition of a single MPMCT gate. However, it has not been studied intensively how to decompose many MPMCT gates efficiently at the same time. Thus, this paper studies what is an efficient decomposition method when we have many MPMCT gates. We consider two situations to reduce T-count when we need to decompose many MPMCT gates. Then, we propose a heuristic method to reorder MPMCT gates if possible so that we can find the two situations as much as possible. Our preliminary experiments show that our heuristic can reduce T-count drastically.","PeriodicalId":421588,"journal":{"name":"2020 IEEE 50th International Symposium on Multiple-Valued Logic (ISMVL)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122204587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While there are several techniques for quantum circuit simulation, many state-of-the-art simulators rely on an array-based simulation approach. However, this array-based approach has exponential memory complexity with respect to the number of simulated qubits. To address this drawback, complementary approaches based on decision diagrams have been proposed. While these approaches allow simulating circuits that could not be simulated before, they come with their own drawbacks. Unfortunately, no detailed case study has been conducted to date, which compares those complementary approaches and their respective strengths and weaknesses. In this work, we are addressing this by providing a survey on both approaches as well as a detailed case study on their respective performances.","PeriodicalId":421588,"journal":{"name":"2020 IEEE 50th International Symposium on Multiple-Valued Logic (ISMVL)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133248977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The preparation of such states itself requires a computation performed by a quantum circuit. In this paper, we investigate the automatic state preparation of a specific subset of quantum states that are uniform superpositions over a subset of basis states, called uniform quantum states. We exploit that such states can be represented using Boolean functions and present a recursive algorithm based on functional decomposition. When using binary decision diagrams as function representation, we can enable fast and scalable quantum state preparation with respect to the size of the decision diagram. We show that the algorithm can find quantum circuits for functions, where state-of-the-art algorithms cannot be applied anymore.","PeriodicalId":421588,"journal":{"name":"2020 IEEE 50th International Symposium on Multiple-Valued Logic (ISMVL)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128311163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed method formally verifies the correctness of circuit functionality (i.e., the inputoutput relations given as GF-polynomials) by checking the equivalence between a specification and a gate-level netlist. In the proposed method, we represent a netlist as simultaneous algebraic equations and solve them based on a new polynomial reduction method efficiently applicable to arithmetic over extension fields ${{mathbb{F}}_{{p^m}}}$, where the characteristic p is larger than two. Using reverse topological term order to derive the Gröbner basis, our method can complete the verification even when a target circuit includes bugs. Our experimental results show that the proposed method can efficiently verify practical ${{mathbb{F}}_{{p^m}}}$ arithmetic circuits, including those used in modern cryptography.","PeriodicalId":421588,"journal":{"name":"2020 IEEE 50th International Symposium on Multiple-Valued Logic (ISMVL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130040966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
