The last talk of the session in the Hahn hall is by Dhruv Devulapalli. He’s keeping the audience engaged with some polls.

Next in the Hahn Hall, Miriam Backens gave a crystal clear talk on an algebraic formulation of Pauli flow, with plenty of examples to help the audience follow along.

In the Hahn hall a session on circuits & compiling is ongoing. It starts with a talk by Ali Javadi-Abhari on Surpressing Correlated Noise in Quantum Computers via Context-Aware Compiling. The IBM slides always look so good.

It's lunchtime on Day 3 and now seems like an excellent time to thank our wonderful sponsors who supported, participated in, and made this event happen! #QCTiP

Our second plenary session has Nathan Wiebe both captivating and entertaining our audience -- showing how exponential improvements in gradient-based quantum optimisation are possible. The trick? Don't look at your gradients, go fully quantum! #QCTiP

The last session of the day is an industry panel.

The #QCTiP industry session has started. First up is Fedor Šimkovic from IQM.

Last talk before lunch in the Hahn Hall -- Dan Mills wonders how we can trust the outputs of quantum computers (and conveniently breaks down the themes of the talk by font!) #QCTiP

Nikolai Miklin in the Hahn Hall reckons we can certify quantum gates by quizzing the quantum system ❓❔❓❔ #QCTiP

In the Goethe hall a session on quantum algorithms has started. The first talk is from Laura Clinton on QPE without controlled unitaries.

Kicking off Session 2 in the Hahn Hall we have Christopher Vairogs who has many questions (and answers) about how to shuttle multipartite entanglement onto a subsystem of your state by performing measurements #QCTiP #QCTiP2025

Had been feeling like there weren't enough Fermions so let out a big sigh of relief when Alexander Schuckert came up to tell us about fermion-qubit fault tolerant quantum computing in the Hahn Hall #QCTiP

The magic party continues in the Hahn Hall but in a different context -- Seok-Hyung Lee talking about a nice scheme to implement magic state distillation using colour codes #QCTiP

Next up is a local favourite who came to the conference by bike. Marcel Hinsche will talk about single-copy stabilizer testing.

Kicking the day off in the Hahn hall we have Nadish da Silva tackling one of the OG problems in quantum info -- classifying the gates of the Clifford hierarchy! #QCTiP

Next up is Soumik Ghosh giving a talk on the hardness the learning quantum circuits and cryptographic applications. He starts off by explaining what it means to learn a random quantum circuit.

It’s day 2 of #QCTiP. The quantum learning session in the Goethe hall starts with a talk from Alireza Seif on entanglement-enhanced learning of quantum processes at scale.

The last talk of the day is given by Werner Dobrautz. He apologises for the long title.

Finishing off the day in the Hahn Hall, Frederik Nathan is going to tell us how to turn dissipation from our enemy into our friend using GKP qubits 🥰

A Quandela double-header in the Hahn Hall with Boris Bourdoncle talking about how to minimise resource overhead in fusion-based quantum computation using hybrid spin-photon devices #QCTiP

Oriel Kiss tells us about early fault-tolerant quantum algorithms in practice. Wow, he has incorporated the conference name in his title.

Kicking off the final session of the day in the Hahn Hall is Theo Dessertaine looking at tailoring error correction codes to the photonic architecture of Quandela #QCTiP

The last session of the day in the Goethe hall has started with a talk from Javier Robledo Moreno

The last talk of the session in the Hahn hall is from Stefano Polla on error mitigation and circuit division for early fault-tolerant quantum phase estimation.

To conclude the second session in the Goethe hall, Jeffery is telling us how to prepare Dicke states with mid circuit measurements.

The Goethe hall is full also for the second talk of the session, by Xin.

The second talk in the Hahn hall is from Daniel Miller on experimental measurement and a physical interpretation of quantum shadow enumerators.

In the Goethe hall the afternoon session is started by Noah. Fourier transforms a play a big role in his talk on Decoded Quantum Interferometry.

After a delicious lunch, Zhenyu starts off the parallel session in the Hann lecture hall with a talk on quantum error mitigation for sampling algorithms.

Over in the Hahn Hall we have Pascal Baßler presenting nice and comprehensive methods for Hamiltonian engineering! #QCTiP

Laura gives the last talk of session A on Demonstrating real-time and low-latency QEC with superconducting qubits

Next up in session A is Lucas Berent telling us about LSD, a popular topic in Berlin.

In parallel Timo Eckstein tells us how to reduce shot noise requirements for simulations of lattice Hamiltonians! #QCTiP

Session A starts with a talk by Alec Eickbush on “Implementing surface codes using time-dynamic circuits”.

Vlad Sivak gives the first scientific talk of the conference. On quantum error correction below the surface code threshold.

Jens Eisert kicks off the conference with a welcome talk. Jens highlights the significance of Berlin and the Harnack house in the history of quantum mechanics.
