Hay from the Haystack: Explicit Examples of Exponential Quantum Circuit Complexity

نویسندگان

چکیده

The vast majority of quantum states and unitaries have circuit complexity exponential in the number qubits. In a similar vein, most them also minimum description length, which makes it difficult to pinpoint examples complexity. this work, we construct constant length but We provide infinite families such that each element requires an two-qubit gates be generated exactly from product where same is true for approximate generation elements family. results are based on sets large transcendence degree discussed tensor networks, diagonal maximally coherent states.

Quantum Circuit Complexity

We propose a complexity model of quantum circuits analogous to the standard (acyclic) Boolean circuit model. It is shown that any function computable in polynomial time by a quantum Turing machine has a polynomial-size quantum circuit. This result also enables us to construct a universal quantum computer which can simulate, with a polynomial factor slowdown, a broader class of quantum machines ...

On The Complexity of Quantum Circuit Manipulation

The stabilizer class of circuits, introduced by Daniel Gottesman, consists of quantum circuits in which every gate is a controlled-NOT (CNOT), Hadamard or phase gate [5]. These circuits have several interesting properties. For example, they are robust enough to allow for entangled states, yet they are known to be simulable in polynomial time by a classical computer. These circuits also naturall...

the effect of task complexity on lexical complexity and grammatical accuracy of efl learners’ argumentative writing

بر اساس فرضیه شناخت رابینسون (2001 و 2003 و 2005) و مدل ظرفیت توجه محدود اسکهان (1998)، این تحقیق تاثیر پیچیدگی تکلیف را بر پیچیدگی واژگان و صحت گرامری نوشتار مباحثه ای 60 نفر از دانشجویان زبان انگلیسی بررسی کرد. میزان پیچیدگی تکلیف از طریق فاکتورهای پراکندگی-منابع تعیین شد. همه ی شرکت کنندگان به صورت نیمه تصادفی به یکی از سه گروه: (1) گروه موضوع، (2) گروه موضوع + اندیشه و (3) گروه موضوع + اندی...

On the Quantum Circuit Complexity Equivalence

Nielsen [3] recently asked the following question: ”What is the minimal size quantum circuit required to exactly implement a specified n-qubit unitary operation U , without the use of ancilla qubits?” Nielsen was able to prove that a lower bound on the minimal size circuit is provided by the length of the geodesic between the identity I and U , where the length is defined by a suitable Finsler ...

The informational complexity of learning from examples

This thesis attempts to quantify the amount of information needed to learn certain tasks. The tasks chosen vary from learning functions in a Sobolev space using radial basis function networks to learning grammars in the principles and parameters framework of modern linguistic theory. These problems are analyzed from the perspective of computational learning theory and certain unifying perspecti...
