Quantum Networks Summit 2027 is the fourth edition of an international technical forum on quantum communications, photonics and secure networking, held at the Palais des Congres de Paris. It brings together telecom operators, research institutes, technology vendors and public bodies working on quantum networking and quantum-safe infrastructure. The 2027 programme is organised across three progressive layers: protocol-level changes to existing classical networks, the introduction of quantum primitives into those networks, and fully quantum network architectures. Specific technical emphasis falls on quantum memories, repeaters, transducers and entanglement distribution, alongside the practical question of how quantum key distribution is deployed over installed fibre. The summit sits at the point where quantum research meets carrier engineering, so the audience mixes academic groups with the operators and equipment makers who would have to build any real quantum network. For engineers and strategists tracking post-quantum security and long-distance entanglement, this Paris quantum computing conference offers a concentrated two-day view of where the field currently stands.
Quantum Networks Summit 2027 takes place April 7–8, 2027 in Paris, France.
Quantum Networks Summit 2027 is an in-person event.

Travel questions? See Good to know in the travel guide below.
The Palais des Congres sits at Porte Maillot on the northwestern edge of Paris, a business district rather than a tourist one, which suits a two-day technical summit. Early April is unsettled but genuinely spring-like, with afternoons near fifteen degrees and the Bois de Boulogne coming into leaf a few minutes west. Delegates get quiet hotels and fast links into both the centre and La Defense.
Charles de Gaulle (CDG) is the main gateway, roughly forty minutes from Porte Maillot by taxi or via RER B with a connection. Orly (ORY) is about the same to the south. The venue has its own RER C station and Metro line 1 stop, putting the centre fifteen minutes away. Eurostar and TGV services arrive at Gare du Nord and Gare de Lyon, both a straightforward Metro ride.
Skip the taxi queue — pre-book a fixed-price airport transfer with Welcome Pickups. Exploring beyond the city? compare rental cars on Auto Europe.
Wi-Fi is reliable across the congress centre and most business hotels around Porte Maillot. Visitors from outside the European roaming zone will find an eSIM the least troublesome way to keep data running between the venue and the centre. Set up an eSIM with Airalo before you board and you're online the moment you land.
Musee Marmottan Monet. A townhouse museum in the sixteenth arrondissement holding the largest collection of Monet works anywhere, including the painting that named Impressionism. Ten minutes from Porte Maillot. Ninety minutes is enough, and it stays far calmer than the larger national museums. Tickets on Tiqets →
Parc Monceau. An English-style park a short walk east of the venue, ringed by nineteenth-century mansions and dotted with follies. Early April is when the chestnuts and magnolias come out. Half an hour is plenty, and it is the obvious place to take a call or clear your head between sessions.
Fondation Louis Vuitton. A Frank Gehry building of glass sails at the edge of the Bois de Boulogne, about fifteen minutes from the venue, showing contemporary art and hosting major loan exhibitions. Allow two hours including the rooftop terraces. Book a timed slot, as walk-up entry is often unavailable. Tickets on Tiqets →
Arc de Triomphe. Two Metro stops from Porte Maillot along line 1, with a rooftop platform reached by a spiral staircase of nearly three hundred steps. The view straight down the Champs-Elysees is the reason to go. Under an hour, and late afternoon light in April is the best of the day.
How do I get from Charles de Gaulle to Porte Maillot?
A taxi takes roughly forty minutes depending on traffic. By public transport, RER B into the city with a connection onto Metro line 1 or RER C reaches the venue directly.
Is the venue far from central Paris?
No. Porte Maillot is on Metro line 1 with the Arc de Triomphe two stops away and the Louvre area about fifteen minutes, so the centre is easily reachable after sessions.
What is the weather like in early April?
Changeable spring weather, with highs around fifteen degrees Celsius, cool mornings and a real chance of showers. An umbrella and a mid-weight jacket cover it.
