Hamiltonian gadgets with reduced resource requirements

Abstract: Application of the adiabatic model of quantum computation requires efficient encoding of the solution to computational problems into the lowest eigenstate of a Hamiltonian that supports universal adiabatic quantum computation. Experimental systems are typically limited to restricted forms of two-body interactions. Therefore, universal adiabatic quantum computation requires a method for approximating quantum many-body Hamiltonians up to arbitrary spectral error using at most two-body interactions. Hamiltonian gadgets, introduced around a decade ago, offer the only current means to address this requirement. Although the applications of Hamiltonian gadgets have steadily grown since their introduction, little progress has been made in overcoming the limitations of the gadgets themselves. In this experimentally motivated theoretical study, we introduce several gadgets which require significantly more realistic control parameters than similar gadgets in the literature. We employ analytical techniques which result in a reduction of the resource scaling as a function of spectral error for the commonly used subdivision, three- to two-body and $k$-body gadgets. Accordingly, our improvements reduce the resource requirements of all proofs and experimental proposals making use of these common gadgets. Next, we numerically optimize these gadgets to illustrate the tightness of our analytical bounds. Finally, we introduce a gadget that simulates a $YY$ interaction term using Hamiltonians containing only ${X,Z,XX,ZZ}$ terms. Apart from possible implications in a theoretical context, this work could also be useful for a first experimental implementation of these key building blocks by requiring less control precision without introducing extra ancillary qubits.

Loop-Oriented Programming: A New Code Reuse Attack to Bypass Modern Defenses

Abstract: Code reuse attacks have become one of the most popular exploitation techniques, and coarse-grained control flow integrity (CFI) is a practical approach used to prevent such attacks. Recently, some new approaches have been proposed to construct call-preceded-ROP attacks to bypass coarse-grained CFI, however, we find that they still fail to bypass shadow stack, which enforces caller-callee semantics to strengthen CFI that constrains the control flow in a much stricter way. Therefore, in this paper, we propose a new code reuse attack, named loop-oriented programming (LOP), aiming to bypass both coarse-grained CFI and shadow stack. Quite different from previous code reuse attacks, LOP collects entire functions as basic building blocks (i.e., gadgets), and chains these gadgets in a way that the control flows strictly follow the process of call-ret-pairing. Specifically, LOP selects a particular function with a loop statement, called loop gadget, to chain all the available gadgets. To demonstrate the effectiveness of LOP, we construct a proof-of-concept exploit against Internet Explorer 8 on 32-bit x86 platform.

Perturbative gadgets without strong interactions

Abstract: Perturbative gadgets are used to construct a quantum Hamiltonian whose low-energy subspace approximates a given quantum k-local Hamiltonian up to an absolute error e. Typically, gadget constructions involve terms with large interaction strengths of order poly(e-1). Here we present a 2-body gadget construction and prove that it approximates a Hamiltonian of interaction strength γ = O(1) up to absolute error e ≪ γ using interactions of strength O(e) instead of the usual inverse polynomial in e. A key component in our proof is a new condition for the convergence of the perturbation series, allowing our gadget construction to be applied in parallel on multiple many-body terms. We also discuss how to apply this gadget construction for approximating 3- and k-local Hamiltonians. The price we pay for using much weaker interactions is a large overhead in the number of ancillary qubits, and the number of interaction terms per particle, both of which scale as O(poly(e-1)). Our strong-from-weak gadgets have their primary application in complexity theory (QMA hardness of restricted Hamiltonians, a generalized area law counterexample, gap amplification), but could also motivate practical implementations with several weak interactions simulating a much stronger quantum many-body interaction.

A man, a gadget, a legacy.

Abstract: The year was 1995. At the San Francisco airport hall, we awaited the flight to Los Angeles, USA, where we would attend another American congress. At halfway point, a group of orthodontists was talking to a gray-haired gentleman. Sited, he demonstrated how to build an appliance he had created — a Lego-like appliance. His smooth and rather weak voice was indeed persevering. The gray-haired gentleman was Carlos Martins Coelho Filho. I have to confess that, the first time we met, his human figure and smooth voice commanded my admiration more than the appliance , the MPA III, 1 did. A few years later, the MPA IV entered the orthodontic field 2 at the same time I established a closer relationship with Prof. Carlos Coelho. A delightful human being who emanated a dazzling light, infinitely amplified by the fact that it originated from a modest, humble and unquestionably intelligent man. As time went by, we became friends. Born in São Luís, Maranhão (Brazil), Carlos received his Master's degree in Orthodontics from the Piracicaba Dental School (UNICAMP). Before that, he used to be an electronics technician. He also increased his income by giving English lessons. He once told me that, as soon as he was approved by the Masters course, he called professor Muller de Araújo, former head of the program, feeling sorry for having difficulties to attend it on the date set for the beginning of the course. The hurdle was financial. He needed time to sell his small electronics workshop and his old Beetle. He never expected to be approved, given the fierce competition and his own personal difficulties. To his great surprise, Prof. Araújo not only accepted his postponed arrival , but also highlighted his qualities and told him it was his own wish, Prof. Araújo's, to count with the presence of that student, given the sacrifice he would make to take the course. Carlos told me this story a few times and I never interrupted him, as his eyes sparkled with the memories of such a dear professor. Perfume of gratitude. He also told me about his first contact with a dental spot welder. It was an imported equipment that belonged to one of his professors. At that time, the device was rather uncommon in Brazil, but the dream of any orthodontist. Carlos applied his knowledge about electronics to create a copy of the welding machine based on …
